Interesting job from the other week, 2019 Jaguar F-Pace 2.0L diesel ingenium came in for an intermittent engine management light diagnosis.
The only code stored P0341-92 camshaft position sensor A circuit range/performance. Now these engines are well known for stretching the timing chains, however stretched chains usually flag up a cam/crank correlation code. It’s usually vehicles between 2016 and 2018 that suffer with the stretched chains and the EML was intermittently on and off not permanently on.
With this in mind a new camshaft sensor was fitted, codes cleared, road tested and all ok.
A few days later customer reported light back on, the same and only fault code stored. Checked for a powertrain control module (engine ecu) software update, module was fully up to date. Listened to the engine starting up from a cold start and picked up a very, very small rattle. A common sign of stretched timing chains.
We stripped the vehicle and inspected the timing chains. The lower chain, that runs the crank and high pressure fuel pump is usually the one that stretches. However upon comparison to the new chain, only minor stretching was found. (See photos)
When the upper and smaller chain that runs the camshafts was inspected, it was over half a link stretched compared to the new chain. Confirming the fault is down to stretched chains!
Unusual to see on a 2019 car, flagging a different fault code and stretching the upper chain instead of the lower. This is definitely one to look out for now and anyone in the market for a JLR product with the 2.0L diesel ingenium engine to be mindful of. This vehicle only had 40k on the clock as well.
All new and genuine parts fitted, oil and filter change also carried out as precaution/good working practice.
