103 TDI 2009 inttermitent stalling and failed starting

[Jamig]

Hey Guys

I have a strange fault with my Golf TDI, every now and then the car stalls and won't start or will after long persistent cranking. Then will function fine for weeks after without any issues at all.

I did take it to VW Specialist Garage to get fault codes checked and the Mechanic told me the intake manifold was showing an error due to the throttle sticking. Apparently this will get worse but the really bad news is to replace will cost around $1500!

Has anyone else experienced this and/or knows of a cheaper fix\solution or is this just standard VW?

Thanks in advance

Yes the inlet manifold flap error is pretty common on the TDI's. Faulty inlet manifolds are pretty common on the Mk6 GTI's too. You can buy the parts you need online from a place like Darkside Developments (see link below) for about 1/2 of the price you can locally and that will save you some cash.

This inlet manifold is on special saving $180 GBP: Darkside Developments - Genuine 2.0 16v TDI PPD170 Intake Manifold

And here is a link to a product that claims to fix certain problems with the inlet manifold on the TDI's....might be worth looking into: A fix for CR TDI fault code P2015 intake manifold flap; implausible signal

Thanks Lucas_R. I'm going to take the car to another garage first for a second opinion but excellent advise. I'm also based in Melbourne Australia so anything this side of the water would be handy

I just had a delivery from the Darkside guys this month which only took 5 days to land
That's including a weekend in between
They only use quality parts, worth waiting a few extra day for

That's incredibly quick from the UK, where in OZ are you?

I'm in Perth
They use DHL so that doesn't really matter

Cool, so Melbourne should be just as quick. How much was shipping?

OK, thing is the inlet manifold tumble flaps are just a cylinder filling to suit revs thing, they can't stall the car. The thing likely to stick is the EGR flap, diesels don't have a throttle flap. Your car will stall because of a fuel starvation, or the EGR flap is cutting the air flow, which is the most likely thing. Is the fuel filter OK / been serviced as per the schedule, they get filthy by 50,000kms.

Put in a can of diesel specific upper intake cleaner from Supercheap - they may have to order it in as most only stock the petrol one, and see if it helps.

Car just had it's major 5 year/115,000km service so fuel filter was replaced then so I'm doubting the fuel filter. Maybe the EGR flap then? At least that sounds a bit cheaper then a complete manifold! So, does the cleaner your suggesting clean out the EGR valve or this is purely fuel related?

I experienced symptoms again today actually although this time i started car no problems and then half way through the journey the car started to loose power like it was stuttering or firing on 3 cylinders, I backed off the throttle and as it started loosing power it picked up again and then was fine.

EGR is sticking and starving the air I reckon, spray goes into inlet, fuel cleaners don't help as the fuel is injected directly to the cylinder. You can piuck up a new/used EGR valve off ebay UK for not much at all, but try and clean your one first!

Thanks Greg. What type of cleaner would you recommend for the EGR Valve? Also do you know where exactly it's located?

Liquimoly 2730 is the code I use, and you just spray it in after the MAF sensor, ideally just before the turbo down the PCV oil blow by connection, this is the big 25mm hose sticking straight up over the back of the engine on the passenger side just before the turbo charger. Follow the instructions on the can, can't hurt.

I thought we should spray it just before the ASV/EGR assembly?

Ok so have been driving the car since my last post and there has been none of the symptoms above. I ended up taking it to Dandyvolks, the mechanic there checked the codes and none of the previous ones were present only the throttle flap sensor (don't quote me on that). He checked to make sure it wasn't sticking, which it wasn't and then carried out some more tests via the computer.

At the end of all the testing everything passed and was ok so he advised me to basically give it a good blast out as he said it's more than likely carbon build up. This I suspect is true as my daily commutes are a mere 12km to work and the same back, this is all city traffic driving too. When I left the garage to drive home which is a 40min drive to Box Hill I made sure keeping the revs above 3-4000 for almost 15min then towards the remainder of my journey through a residential part I held the gear in 2nd and took the revs all the way up to the red line and held it there for a couple of minutes. I must say since doing all that the car has been performing really well maybe even better than before.

I believe thats referred to as an Italian tune up.
