Audi service schedule by engine

Timing chain

No scheduled replacement

NOT on the task list — added because porsche.json's 2.9 EA839 entry is Porsche-only, so an RS4/RS5 at 2,894cc gets no answer. motor-car.net: the 2.9 is the EA839 shortened by 3 mm of stroke to '2894 cc', 'four overhead camshafts driven by a timing chain', used in the Porsche Panamera II / Cayenne III 'plus Audi RS models (RS4 B9, RS5 F5)' (C-S25). The 2.9 EA839 chain kit — two timing chains, two tensioners, three guides, 'Engine Rear' — is sold against the Porsche applications of the same engine (C-S52). No belt part found. No replacement interval. Interference not stated. Years are the RS5 F5 / RS4 B9 run as commonly dated; not fetched from an Audi UK source.

Timing chain

No scheduled replacement

Four simplex roller chains at the rear of the engine; no replacement interval published; tensioner described as the weak point (R12). Interference status not stated in any fetched source. Re-sourced 2026-10-01: Laser Tools 4772 for the '2.7/3.0L TDi and TDi CR … chain driven diesel engine' with camshaft holding tools (ASB, BKN, BMK, BUN, CAPA…; W-S47), Laser 7588 for 2014-on codes (CRTC, CVMD, DCPC, DDXC…) 'all the timing tools required for chain removal' (W-S48), and a Lymm 3.0 TDI kit with 206- and 136-link chains (CDUC, CDUD, CJMA, CRCA…; W-S50), with AUTODOC chain kits for the A6 C6 ASB (87) and CDYA (48) (W-S51, W-S53) — but Laser 6849 is a 'Fuel Pump Drive Belt Kit' for 2007-2012 codes (CASA, CCWA, CDYA, CARA…; W-S49) and AUTODOC also lists 82/83-tooth toothed belt kits 'Driven Units: Injection pump' for the ASB and CDYA (W-S52, W-S54), so these engines also carry a separate toothed belt driving the high-pressure pump (no interval found).

Timing chain

No scheduled replacement

Chains drive the camshafts; no replacement interval published. CAMSHAFT test: motor-car.net — 3.0 = '2995 cm³', 84.5 x 89.0 mm, 'four overhead camshafts driven by a timing chain', fitted to Audi A6/A7/A8 from 2017-18 and the 'VW Touareg III from 04/2018' (C-S25); Euro-AMP sells a '2 Timing Chains, 2 Tensioners, 4 Chain Guides' kit for S4/S5/SQ5/A6/A7/A8/Q7/Q8 3.0 EA839, 'Rear of Engine (Chain Driven System)', synchronising 'the crankshaft and camshafts' (C-S27). The Touareg eHybrid / R eHybrid PHEVs use the '3.0-litre, six-cylinder turbocharged' petrol engine (VW, C-S26); DVLA files them HYBRID ELECTRIC at 2995cc. hybrid is FALSE on purpose: the matcher only gates rows marked hybrid against non-hybrid cars, never the reverse (engineRowMatches: `if (row.hybridOnly && !row.mildHybrid && !v.hybrid) return false`), so one non-hybrid row reaches the petrol V6 and the plug-in alike, and a hybrid-only copy would add nothing but a duplicate answer. OVERLAP: 2016-2019 Audis at 2995cc also match the supercharged EA837 entry — both are chain-driven, so the timing answer agrees. Interference not stated. This is a VW-Group entry rather than a brands amendment to porsche.json's EA839 because that entry carries Porsche-published oil/plug/brake intervals.

Timing chain

No scheduled replacement

Chain-driven with hydraulic tensioners; no replacement interval; STR suggests monitoring from 100,000 km (T21). Interference not stated.

Timing chain

No scheduled replacement

Chains drive the camshafts; no replacement interval published by any fetched source. CAMSHAFT test: Laser Tools 7558 kit exists 'to lock the engines in their timed position so the camshaft drive chain can be safely removed and replaced' on the Audi 4.0 TFSI, codes CEUA, CEUC, CGTA, CRDB, CTFA, CTGA, CTGE, CWUB, CWUC, DDTA, A8/RS6/RS7/S6/S7/S8 2012-2018 (C-S18). OPPOSITE-KIT test: only chain parts/tools found; no belt part surfaced. CAPACITY: 3,993cc — the 2012 Bentley V8 built on this engine is '3993cc', 'a development of the engine Audi has fitted to the S6, S7 and S8' (C-S17) — distinct from the 3,996cc EA825 that replaced it from 2018, so DVLA cc separates the two. Interference not stated.

Timing chain

No scheduled replacement

Chains drive the camshafts; no replacement interval published. CAMSHAFT test: Audi's own RS 6 press text — 4.0 TFSI, '3,996' cc, 86.0 x 86.0 mm — states 'The chains of the valve gear are driven by a geared intermediate shaft' (C-S20), i.e. a gear stage from the crank to an intermediate shaft, then chains to the camshafts; motor-car.net: 'four overhead camshafts driven by a timing chain', first Audi use 'June 2018 for the Audi A8 60 TFSI' (C-S24). LAMBORGHINI: the Urus is '3,996 cm³' twin-turbo V8 (C-S21) and its OE timing diagram lists only timing chains, drive chain, tensioners and rails — no belt (C-S22). Interference not stated. This is a separate VW-Group entry rather than an amendment of porsche.json / bentley.json's EA825 entries because those carry Porsche- and Bentley-published oil, plug and brake-fluid intervals that must not render on an Audi or a Lamborghini.

Timing chain

No scheduled replacement

Chains drive the camshafts; no replacement interval published by any fetched source. CAMSHAFT test: the R8 V8 / RS5 kit contains a 'Main Timing Chain', 'Accessory Timing Chain', 'Bank 1 Timing Chain' and 'Bank 2 Timing Chain' — i.e. a separate chain to each bank's camshafts (C-S16); a four-chain kit is sold for codes BAR, BVJ, CAUA (A6, A8, Q7, S5, VW Touareg 4.2 V8), whose seller says 'timing chains stretch and guide rails fail at some point of this motor's life-cycle' (C-S15). OPPOSITE-KIT test: no timing-belt part surfaced for the 4.2 FSI in the catalogues searched. Do NOT confuse with the older 4.2 V8 40v (4,172cc, ANK/AQJ/ARS/ASG, 1998-2004) which Gates lists with a timing BELT (C-S1) — different capacity, so DVLA separates them. BNS (RS4 B7) is included on the strength of the shared 4,163cc FSI design; no fetched catalogue named BNS explicitly. Interference not stated.

Timing chain

No scheduled replacement

Chain-driven; no replacement interval published. OPPOSITE-KIT test (decisive): AUTODOC lists 33 timing CHAIN kits for the A8 D3 4.2 TDI (BVN) — e.g. 'Number of chains: 4', 'with chain tensioner, with slide rails' (C-S29) — while its timing BELT kit page for the same car says 'Unfortunately, item Timing belt kit for AUDI A8 (4E2, 4E8) 4.2 TDI quattro 240 KW is not available' (C-S30). CAMSHAFT test: Sealey's VSE6181 'Chain Drive' kit is for 'service work on timing chain, cylinder head, HP pump and engine timing' on the 4.2D TDi V8, codes BVN, CCFA, CCFC, CDSB, CKDA (C-S28). PORSCHE: the Cayenne Diesel S uses the '4,134cc V8 twin-turbo', 'Audi donated' (C-S31). Note Sealey's code list also includes CZAA/DHVA, which are the later 4.0 V8 TDI (different capacity, not this entry). Interference not stated.

Timing chain

No scheduled replacement

Chains drive the camshafts; no replacement interval published by any fetched source. CAMSHAFT test: the OE Audi chain 06E109465BK/AS for the 2017-2023 R8 and 2015-2024 Huracán 'wraps around the right side cam sprockets and RH center sprocket' ('the upper right side chain'), and the seller notes it also fits the Gallardo (C-S14). The same chain family (06E109465AN/AP/AM/AQ, four chains, three tensioners) is sold as a kit for the S6 5.2 V10 (BXA) and S8 (BSM) alongside the 4.2 FSI V8 (C-S15). OPPOSITE-KIT test: no timing-belt part surfaced for any 5.2 V10 application in the catalogues searched. Interference status not stated. Chain position/removal effort not stated by a fetched source.

Timing chain

No scheduled replacement

NOT the 1,197cc 1.2 TSI: this is the naturally aspirated three-cylinder MPI (6-valve SOHC / 12-valve DOHC). CAMSHAFT TEST: Sealey's VSE5921 kit holds the camshaft for '1.2, 3-cylinder, 6 and 12 valve chain drive engines' and lists AWY, BBM, BMD, CHFA, CHFB (6v) and AZQ, BME, BXV, BZG, CEVA, CGPA, CGPB, CJLA (12v) (J-S20); ContiTech's procedure for the Polo 1.2 (BMD) locks the camshaft with OE T10120 and pulls 'the timing chain together with the camshaft sprocket', with a separate chain to the oil pump (J-S21, J-S22). OPPOSITE-KIT TEST: AUTODOC lists ~19 chain kits for the Polo 6R 1.2 CGPA/CGPB ('Driven Units: Camshaft', 130-link chain) and its belt-kit pages for both carry the 'Unfortunately, item Timing belt kit … is not available' banner (J-S23, J-S24); the Polo 9N 1.2 BZG and BBM have chain kits (118/130-link cam chain plus 66-link oil-pump chain) (J-S25). No manufacturer replacement interval found. LDS notes a change from a simplex to a duplex chain on 'Later 12v engines' (J-S26) — a running revision, dates not given. Chain wear: ContiTech says only, in general, that 'Timing chains can lengthen as their service life increases' (J-S21); no fetched allowed source states an engine-specific chain-stretch defect for this MPI engine, so none is claimed here. Capacity: catalogues give 1,198cc for the VW applications (DVLA reported 1,198 for a 2010 Polo) and 1,197cc for several Skoda/SEAT applications (J-S26) — the entry is held at 1,198 so it cannot collide with the 1,197cc TSI entries (see unresolved). Interference not stated by a fetched source.

Timing chain

No scheduled replacement

Roller chain, SOHC; no scheduled replacement published. OPPOSITE-KIT evidence added 2026-09-30: AUTODOC lists 190 timing chain kits for the Polo 1.2 TSI 105 CBZB (C-S50) against 3 chain items for the EA211 CJZC that replaced it (C-S49). Re-sourced 2026-10-01: Laser Tools 6858 for CBZA/CBZB/CBZC 'locks the crank and camshaft in their timed positions to enable the user to remove and replace the camchain' (W-S38), and AUTODOC's belt-kit page for the same Polo 6R 1.2 TSI CBZB reads 'Unfortunately, item Timing belt kit … is not available' (W-S39), completing the opposite-kit test against C-S50's 190 chain kits.

Timing chain

No scheduled replacement

2015-ONLY CONTINUATION of the 'EA111 1.2 TSI' entry (items copied verbatim), gated with modelExclude so the POLO and FABIA — EA211 (belt) for all of 2015 — no longer match it. Polo: the facelifted Polo (6C) with the new 1.2 TSI 90/110 PS went on order April 2014 with deliveries from June 2014 (C-S47); AUTODOC lists the 6C 1.2 TSI 90 as CJZC (an EA211 code in this file) for 2014-2017 (C-S49) and the earlier Polo's 1.2 TSI 105 as CBZB (EA111) with 190 chain kits (C-S50). Fabia: Škoda UK dates the Mk2 '2007-2014' and the Mk3 (1.2 TSI 90/110) '2014-2021', UK sales from January 2015 (C-S48). Which of the remaining models really still used the EA111 in 2015 was not established model by model (see unresolved); they keep the both-candidates answer they had before. Original note: Roller chain, SOHC. No scheduled replacement published by any fetched source. Re-sourced 2026-10-01: Laser Tools 6858 for CBZA/CBZB/CBZC 'locks the crank and camshaft in their timed positions to enable the user to remove and replace the camchain' (W-S38), and AUTODOC's belt-kit page for the same Polo 6R 1.2 TSI CBZB reads 'Unfortunately, item Timing belt kit … is not available' (W-S39), completing the opposite-kit test against C-S50's 190 chain kits. Laser 6858 dates the CBZx engines '2009-2016' and lists Golf VI to 2015, Caddy, Touran, Yeti, Roomster, Rapid, Altea, Ibiza 6J and Toledo to 2015 and Jetta to 2018 — consistent with this 2015-only entry.

Timing chain

No scheduled replacement

Roller chain designed for engine life; no OE replacement interval found. Independents report chain/tensioner noise and stretch from ~60,000 mi / 50-100k km (R10, R11). Interference status not stated in fetched sources. Re-sourced 2026-10-01: Laser Tools 6965 timing chain wear kit for 'VAG 1.4 TSi Direct Injection chain driven twin cam petrol engines' with an exhaust camshaft holding disc (W-S40); AUTODOC lists 256 chain kits for the Golf VI 1.4 TSI CAXA and its only 'timing belt kit' item is a 6-rib water-pump kit (W-S41, W-S42).

Timing chain

No scheduled replacement

Chain drives the camshafts; no replacement interval in any fetched source. YEARS: from the TT RS (8J, CEPA) onward — Prorace dates the 8J range 2006-2014 but lists the 2.5 only as the TT RS's CEPA/CEPB; the 2009 start is the TT RS's arrival, not a fetched date. CAMSHAFT test: Prorace's kit is 'chain, tensioner, guides and crank/cam sprockets' (C-S13) and BAR-TEK's timing-CHAIN change tool set includes a camshaft locking pin (T40070 pattern) and a camshaft adjuster holding tool (C-S12). OPPOSITE-KIT test: INA timing chain kit listed against CEPA/CZGB/CZGA/CTSA/CEPB at 2480cc (C-S11); no cam-belt part surfaced for this engine in any catalogue searched (AUTODOC not checked for this vehicle). Interference not stated.

Timing chain

No scheduled replacement

Chain drives the camshafts; no replacement interval published by any fetched source. CAMSHAFT test: Sealey's VSE4242 'Chain Drive' kit for the 1.8 TSi/TFSi codes carries the locking tools 'for both types of timing chain tensioner' and the camshaft control-valve tool (C-S6); Lymm sells a timing CHAIN kit with gears for BZB, 1798cc (C-S7). OPPOSITE-KIT test: AUTODOC lists 222 timing chain kits for the Octavia Mk2 1.8 TSI (C-S8) AND 20 'timing belt kits' (C-S9) — but every belt kit shown is a 'Water pump and timing belt kit' (ContiTech CT1143WP3, INA 530 0845 30), and the CT1143 is the 'toothed belt that connects the waterpump to the balance shaft' (C-S10). That small belt drives the water pump only, not the camshafts, so the 'both kits' result does not make this a belt engine. There is also a separate oil-pump chain (Sealey's kit includes 'a tool for the oil pump chain tensioner', C-S6). Interference status not stated by any fetched source for the 1.8. MODELS: only the Octavia Mk2 (2007-2013) and Superb Mk2 (2008-2015) 1.8 TSI are fitment-confirmed at 1798cc (C-S7); the other models are the 1.8-capable lines in Sealey's combined 1.8/2.0 application list (C-S6), and years 2007-2018 are bounded by those lists.

Timing chain

No scheduled replacement

Chain, no scheduled replacement (T20). Gen 1/2 (c.2008-2012) tensioner defect, revised part 06K109467K from late 2011/mid 2012 (T20). Interference per T20 and T16 ('2.0T'). Re-sourced 2026-10-01: Laser Tools 5981 'removal and replacement of the timing chain and camshaft sprockets on the 1.8 and 2.0L TFSi and TSi' (CAWA…CCZB…CJXA…DNUE; W-S43) and Laser 6053 timing chain tension lever (W-S44); AUTODOC lists 169 chain kits for the Golf VI GTI CCZB, while every item in its 'timing belt kit' category is a 54-tooth, 12 mm belt with 'Driven Units: Water Pump' (W-S45, W-S46) — a toothed water-pump drive belt, not a camshaft drive.
