Help please

Hi guys please can anybody help, I have just bought a 2006 x type 2.0 diesel 1 owner with 83 thousand on the clock, the problem she has is when I come to start her up it’s not an instant start she seems to labour into life with slow engine idle for about 10 seconds, no engine management lights are on and she seems to run fine, it’s just the start up , hope I haven’t bought an expensive problem to fix, any help would be great thanks

Hi Roy, 
Welcome to the Forum.

if youve come from driving petrols/arent familiar with diesels of this era...Wait for the glowplug light to go out before turning the key to the start position,  then it should be almost instant start, if not id be looking at glowplugs with view to replace the set.

Thanks for that but I did have a diesel before this, I do wait for the glow light to go out before starting, she does fire up but the revs seem to take to long befor normal rpm, if I need a set of glow plugs how much at garage will that cost ? I just need her fixed 

thanks for your help

I'm not 100% au fait with the particular engine but id expect glow plugs to cost no more than about £50 for a reputable brand and no more than an hours labour to fit.

 

Do the symptoms only happen from cold start or is it every time you start the engine regardless of engine temp?
Do you notice an increase in black or blue smoke from the exhaust when experiencing these issues?

Also something to bear in mind with laboured starting and lumpy idle is it *could* be Fuel or Air related, my experience with other modern diesels is swirl flaps in the intake, it could be a vacuum control issue where you have a vacuum leak or a mechanical problem but the mechanical issue would tend to keep rough idles and not rectify themselves after 5-10 seconds. Where as a vac leak could perceivably take 5-10secs to pull down to a required 'pressure'.

if its fuel related, then it could be a whole miriad of things from a simple Non Return Valve to an Injector. but these are generally few and far between.

I think the best thing for you to consider would be to take it to your local diesel specialist and see if they have any suggestions of what it could be before forking out any money for possibly an incorrect diagnosis.

Thank you for that, the start up problem is ALL THE TIME ( hot or cold engine) seems to run fine, But thanks again I’ll run it to my local garage Tuesday ( I work nights ) 

cheers

Ok so that makes me question that it may very well not be the glowplugs. Glowplugs only really make a difference to cold start scenarios.

I hope its something easy and relatively simple to fix :) report back with what they suggest/ what they find!

Perhaps an obvious response but maybe it would be worth checking the battery for both age and correct size. There's so much that depends upon the battery, especially when starting up and if you've just bought the car, it always pays to ensure you have the most appropriate and lively power block and not some old knackered piece of kit that the vendor wanted to get rid of and swapped it between viewing and collection. It happens!

I would give it a good service, engine oil and filter and air and fuel filters and use only genuine jaguar filters.

Up date, just got jag back from the garage, re start up problem new glow plugs fitted all seems fine now, thanks for all your help guys
