Hi all, any advice on this would be appreciated.

 

Last year, my  2005 superb 1.9tdi 130 hp started smoking badly when i was driving and had towed to a garge here i was told the turbo was gone, so i had an new turb fitted.

 

But ever since, the car would smoke (blue to grey) and judder the firt minute from cold start and then behaves normally once the engine is warm.

 

I took it back to the mechanic who checked it with computer a couple of times and said everything was ok and that i should drive it on the motorway to clear off any dirt!! I folowed his advice nut the problem persisted....then i prked the car unused for 6 months.

 

I restarted using it in july this year when it carried on the same pattern...only the first minute from cold start is awkward.

 

I drove to europe few days ago where the car started smoking a bit more from cold, and the juddering started happening half of the time even if the car engine is warm!

 

Now the car won't start, and had the help of a mechanic who sprayd a starting stuff into the turbo pipe to start the car....but still we don know the cause..... One minute they say it may be the fuel pump, or a blocked fuel filter, or injectors.....etc...

 

garges are too dear in eu...and don't want to be used cos of despaire. Any idea or suggestions please cos the symptoms are not typical of know fuel system issues i gathetd from the mechanics....and towing the car to a garage for a computer test will mean obligation to drain my  modest bank account!!

 

Please advise....

You really need to get the codes read otherwise you'll start diagnosing by substitution which can be difficult and rather expensive.

 

Juddering from cold and then behaving normally could be a glow plug failing but this would only cause the drop of a cylinder for a second or two.

 

The 1.9pd 130 has a lifter pump and then a high pressure combined unit injector/pump (Pumpe Düse) per cylinder. These engines are usually very reliable but the lifter pumps are know to fail as is the pd wiring loom within the cylinder head although this usually just affects one or two cylinders first. If you have had injector failure it wont be all 4 at once unless it's had a major electrical short and taken out a fuse (worth checking - the later 2.0pd in other VAG cars was known to do this and there was even a recall on these to replace the injectors)

 

When the turbo failed was the intercooler changed? - sometimes the turbo failing can create debris although this should get trapped at the intercooler- but if this is ever ingested by the engine then it won't do it much good. (do a compression test?)- 

 

Also chech the antishudder vacuum operated valve visible from the top under the engine plastic cover - if this sticks/fails it could stop the engine starting (well it is designed to stop the engine without shuddering!!).

 

Can I double check that the cam shaft is turning when you try to start the car (double checking that you haven't had cam belt failure).

 

 

 

 

 

Just realised you've posted in the MKII Forum

Many thanks for taking the time to reply to my query, John.

 

- the intercooler ws not changed, but when i read something online about them being clogged with oil after turbo failure, i asked my mechanic last year if he cleaned the intercooler pip, and he said yes!!

 

- the cambelt was Changed in 2016...and yes the camshaft is turning

 

-  when i asked my mechanic about the glow heaters this year he said since the car i startimg in winter first time then thete is no problem with them!

 

- if it was an injector problem then why the csr was behaving when warm! No missfiring? Even though now after drivimg for 24 hours continuously in europe, the car was juddering intermittently even when engine was warm

 

- not against fimding the error codes..but garages in Europe seem less experienced, and more keen on changing for every minute,

If it's an injector loom issue then it can be temperature, vibration dependant and intermittent. It is a common failure as well but usually shows up on a scan as an injector issue. In addition it can be provoked if disturbed - eg working on the engine. The insulation gets brittle with age when bathed in hot oil. It's also pretty cheap to fix!

Ok I will mention it to mechanic here in europ, he was advising me yesterday to change the diesel filter first believing it  was bloced. But   i had it already changed every two years, last in 2016.

 

The garage owner doesn't agree with the mechanic here, and wants to do 50 euros computer check followed by 110 euros per hour labour!!!  Even the diesel filter i buy for £12 in the uk , is priced 30 euros here!!  That put me off yesterday as it implied giving them a blanksigned  cheque to fill as they wish!

 

The car value and mileage (97000 miles)  is not worth spending that much on it i suppose. And i only have breakown recovey service which i still can use anywhere in europe, but it won't cover parts and labour or any repairs.

 

I poured into the tank yesterday a tin of diesel cleaner and going to ask to mechnic  to help me start it this morning to drive it high rev on motorway to send any dirt into the diesel filter before changing it (if he still insists on doing so), and mention the loom to him.

 

Once gain thanks for your avice, much  valued and appreciated.

With the 1.9 pd 130 97k miles is just run in

Managed to have the car started the day before yesterday by spraying 'Rapid' from Wurth into the intercooler pipe, and it has been starting and running eversince but again smoking and juddering 80% of the time. 

 

The loom you mentioned to me will be the first thing i will hve investigated as soon as i leave Austria and Germany where they charge the prices i qouted in my previous message. If i get the chance to have the car fixed for cheaper in Slovakia or Hungry then will do so, otherwise i hope it will drive me back to the UK in two weeks time fingers crossed.

 

An austrian young mechanic said he could check the diesel filter if blocked, and replace it if need be, however if that's not the cause of the problem, then the loom will need the car booked in his boss"s garage which means 50 euros diagnostics and 110 euro per hour abour plus parts!

 

Will keep u posted, and many thanks as always.

 

 

Hi

finally took my car for a computer test for €20 in Slovakia which gave error code 412 F

saying injector 3 nit working properly!

 

What is interesting is that the car was behaving well 80% of the time before the test, but once the rror was reset by the garage, the car is misfiring badly most od the time....

Gottaa drive it back to the UK cos injectors here are too costly (around 800 euros).

 

I hope the car will serve me for the next 7 days travelling back.

That's usually what a faulty looms throws up as it keeps breaking the circuit to the injector. Change the loom first they fail anyway in time so are worth doing and there is a reasonable chance this is your issue!

Hi

 

I certainly willl start with the loom as per your advice, then test to see if the injector is still giving the same  error, before proceeding with buying a reconditioned injector from ebay.

 

Thanking you yet again for your kind support and advice which has really been priceless when there is no ine to turn to in a foreign land!
