P0008 on Audi
Engine Position System Performance - Bank 1
P0008 on Audi vehicles indicates engine position system performance - bank 1. Au7o has documented this code across 1 Audi model — most commonly on TTS. P0008 means the engine computer detected that Bank 1 of the engine is timed incorrectly relative to where it should be — specifically, the relationship between the crankshaft and camshaft positions on that bank is off. The 'Engine Position System' refers to the components (timing chain/belt, sprockets, tensioners, and the variable valve timing actuators) that keep the camshafts synchronized with the crankshaft. When the computer commands a timing position but the sensors report the bank is out of the expected range, it sets this code. It generally signals a mechanical timing problem on Bank 1 that can affect performance and, if severe, risk internal engine damage. Typical repair costs on Audi range from $2,000 to $12,000, depending on the specific model and root cause.
Common Causes of P0008
- •Stretched or worn timing chain
- •Failed or worn timing chain guides or tensioner
- •Faulty camshaft position (VVT/VCT) actuator or solenoid
- •Low or dirty engine oil affecting timing actuator operation
- •Jumped or mistimed timing chain/belt after service
- •Faulty crankshaft or camshaft position sensor
- •Clogged oil control valve or oil passages
P0008 on Audi by Model
Audi TTS(1 issue)
- Timing Chain Tensioner Failure (EA888 Gen 1/2 - Mk2 TTS)2009-2015
The Audi TTS Mk2 (2009-2015) with early EA888 engines (Gen 1 and Gen 2) suffers from timing chain tensioner failure, the same critical issue affecting A3, A4, and A5 models with this engine. The tensioner's ratchet mechanism wears, allowing the piston to retract when the engine is off. On restart, the slack chain can jump teeth on the camshaft sprockets, causing valve-to-piston contact and catastrophic engine destruction. The signature warning sign is a brief rattle (0.5-1 second) on cold or semi-warm startup as the tensioner takes up chain slack. The TTS's higher output tune puts more stress on the timing chain system, potentially accelerating wear. TTForum.co.uk documents numerous cases of complete engine destruction from ignored timing chain rattle. Early models (2009-2012) with the earlier tensioner revision are most at risk.

What does P0008 mean on Audi?▼
P0008 stands for "Engine Position System Performance - Bank 1." P0008 means the engine computer detected that Bank 1 of the engine is timed incorrectly relative to where it should be — specifically, the relationship between the crankshaft and camshaft positions on that bank is off.
