Golf tdi 2009 1.6 - Injector problem 12 Jun 2017 (Forum)
My car has been with a garage then diesel specialist for 3 weeks now has had all four injectors replaced, egr valve checked, fuel pump checked, new fuel filter (just in case), pressure valve replaced on rail. It is running but 'lumpy' in idle. No fault codes are showing and car apparently thinks it is running ok. Mechanics cannot tell me what is wrong and seem to say it needs emission reprogramming even though it has run for 3 months and about 1000 miles since the emissions is recall without any issue. -

When I bought this vehicle back last summer it would offen run rough on idle as if it was 'misfiring' or was a petrol engine with a plug lead removed. I have lived with the problem but its got a lot worse recently and in 'kangarooing' even when driving normally which it has never done before. -

Jaguar X Type 2.1 2002 - Engine Light on X-Type Jag but car runs fine? 31 Jan 2011 (Forum)
Anyways, I did buy it with the engine light on, I have had a similar thing like this with a VW Bora I had, it was a sensor issue also on a BMW, that was an air bag light. The Engine light is on, however it seems to be running fine, no misfire, just had a full service, new sparks, filters, fully synth oil etc.. but the light is still on. Does anyone know why this could be on, Im getting a diagnostic run on it today/tomorrow but just looking for any pointers as I dont want to be ripped off etc.. -

Rat run - near miss - fear v food 1 Dec 2009 (Forum)
------- made it - although perceived in the languar of retirement relaxation, amongst the lemmings of the morning rush hour, as perhaps a ferret - the poor mans whippet of these Northen climes. A rat run then perhaps? around the brick terraces of autumal dreams and desires of far away places - or at least Magaluff and a few lagers. But no. It ran tail stretched out behind - fast and sleek, across the inner city dual carriageway - up a short brick wall vertically and into the rich pickings of car window excreted burger remains (with French fries) A true rat run then, one fast food place to the other - across a busy road.
