Sounds like an injector copper washer has failed, try lifting some of the sound deadening on the nearside bank and see if you can see any residue or see any blow by with the engine running. |

Thanks just seen can be a common problem on the injectors - Cars going into drop n go car park tomorrow for 2 and bit weeks so will give it a check over when I get home. Presume car will be okay to drive home again - about a 2 hour drive. |

I'd say so, I drove back from the French Alps, approx 1k without any issue, just a bit of fumes in stationery traffic. Easy enough repair, replace the copper washer and o rings as well as the clamp plate and bolts to be sure of a 100% fix. Not expensive for gen parts. |

Thanks man will have a look - car is in airport car park for 2 weeks now so will check it when get back - either that or a loose exhaust clamp? Definitely a puft puft type noise that gets faster with accelerator around the passenger side of the engine - cabin had a strong smell this morning when drove from hotel to airport car park |

The crossover pipes are a bit prone to cracking also, but if the sounds the same when the engine is warm I'd say a copper washer, as usually if the crossover is cracked they tend to seal a bit better when warmed up.

Mine never showed any codes whatsoever, if you just lift the foam insulation on the nearside bank, you'll see fumes and smell it big time when it's running.

JLR obviously stock them, but they're a bosch part and are cheap as chips on ebay, albeit only a couple of quid from JLR. I'd insist the clamp plate and bolts are changed too, as the plate can distort and the bolts stretch. For the small extra cost it's worth it for peace of mind. |

Hi looking at getting this done myself is it a easy DIY job and can you buy a kit with the bolts? |

If one of the injector seals goes (as did mine recently) should I replace all of them (almost 300.000 km in my 2015 L494 diesel - or is it just bad luck, no (little) chance the other seals are going to die also on a short term? |
