On my 2011 MK6 2.0 TDI:

 

My dashboard "coil" warning symbol came on a few weeks ago while I was on a long stretch of dual carriageway, and the car went in to slow mode. 

 

I could keep up with the traffic but no power to overtake anything. 

 

After about 20 miles I got fed up and stopped and after if cooled down it was fine.  

 

Then during the recent MOT and service the garage said it was the EGR.  Soon after the coil icon warning light came on again.

So it needs doing.

Garage quoted about £350 for the part and about £450 for labour (or vice versa).

 

Does anybody know if they can be cleaned, or it is a replacement-only job, and is this a reasonable cost?

(It's a LOT of money!!)

 

Ian

I've read that on the mk6 Golf diesel is pita of a job as engine needs to be lowered which is why they recommend changing rather than cleaning.

Based on my mates 2.0 TDi 140 Passat (which I think has the same engine as my Mk6 2.0 140) it is indeed a PITA job. He got his done for £900 all up. No amount of cycling the valve in VCDS or italian tuning sorted it. TBH, his is nannied around, but it lasted another 4 years before it needed doing again. 

 

It sits at the back of the engine, rear left (lookiing from the bonnet). On his Passat there were options to take the drive shaft out to drop it through the bottom or removing the turbo (and possibly manifolds) to take it out of the top. I am not surprised it needs an engine mount to be removed on the Golf, it is a big piece of kit sandwiched in between the back of the engine and the firewall.

Thank you Thinkpad and Bandit.

It does sound like a hell of a job!  

A local back street garage where the neighbour (who is a bit of a picky perfectionist) works can do it for £750 inc VAT, they said it is a 4.5 hour job!

So based on what you both said, I am going with that.

I don't think I will find anywhere cheaper who I am comfortable with.

Some things just aren't simple or cheap.  But I am not planning on changing the car for a while, so it is money well spent I suppose!

Since it works cold It’s most likely the electronic parts that have had it rather than being blocked, why not just have it disabled on the map? It’s a lot cheaper, a common mod anyway and removes the need to touch anything mechanical

plus it's a lot cheaper and while having it mapped out you might as well go for the extra bhp you can have on a stage 1 map... 

 

it's a diesel it will pass the test better with the egr disabled... just make sure that when you are taking the motorway to use the first 3 gears to the redline.. make it a habit, it'll help keep the engine, dpf and egr clean..

Yup recently done the same on a mk5 but kept the original map, noticeably smoother. Plus stops it happening again if you plan on keeping the car for a decent amount of time.

Op I noticed you’re in Hampshire also, if you need someone to map it out drop me a pm

Well I've had it done now, £780.

The garage did some measurements before and after to make sure it was definitely faulty, and the new one is now giving better results of some description.

The garage man did mention they clog up due to driving styles.  He too mentioned the DPF, which I think is another expensive job to replace.

I have heard about the DFP delete option, but apparently it is now an MOT failure if they notice it has been tampered with.

 

Interesting what you said about disabling the EGR, and "mapping it out".  But I am a worrier, so that doesn't appeal to me!

 

When I got my mk6  2.0 TDI 140BHP, they offered to do the mod to give it 170BHP, it would have been done by some specialist up the road from the garage in Hersham, I think it was AMD TECHNIK, and it would have been about £400 I think, and that included rolling road before and after.  If I'd know how sluggish the Mk6 is compared to my mk4 TDI, I'd have had the stage 1 done there and then!

 

I keep thinking I am going to sell it and change to a petrol mk7, but not done it yet because I can't get my head around only having a 1.4 engine, even if it does claim to be 150BHP.

> big bang... thanks for offer to tweak the map.  Obviously I don't need that any more.

If you know how to set the alarm enable/disable "chirp" so I can turn it on and off from the comfort settings, and you've successfully done it before, I would like to know!

I am referring to the mk6 which annoyingly is silent when setting and unsetitng the alarm

by replacing it you'll be fine for the when got few years... but change your driving style, be more aggressive when it comes to going onto the motorway, use the first  gears to redline. every time and you'll keep the thing in a state that is good enough to not cause problems, about your dpf, there is a dpf and catalytic converter cleaner called CATACLEAN... i suggest you get a bottle (they're less than 15 pounds) add it to a tank and just drive your car as normal... it'll clean both dpf and cat... saves you worrying about those items... 

 

and if that doesn't satisfy you, your next option would be a terraclean with the addition of intake, dpf and egr clean.. will cost you around 180 pounds but once they're done the complete engine, intake, turbo, egr, dpf and cat will be as clean as new items.

 

it sounds expensive for a cleaning session but to be fair (and you should've gone for that first) it would've saved you 600 pounds

 

And i still say map the egr out and go for that stage one map...

Glad to hear your issue is cured either way! Out of interest did they check the back pressure of the dpf when it was in? Yes the chirp is very easy, lots of options for the mk6! I’m sure there’s a forum post somewhere with the full list.

I still agree with northpole, even with a new dpf, I’d have it turned off. It will keep everything else the same, just close the valve that allows it to recirculating those dirty diesel exhaust gases, then if you wanted to sell it you can have it turned back on to keep it stock. No worries of it happening again, £700+ is an eye watering amount!

On the remap I wouldn’t bother paying £400 and getting a rolling road done for a stage 1, only worth it for a true custom map with custom components IMO, you can get a safe well known OTS generic map for £150ish. They don’t push the hardware as much, but as long as you have a healthy car they’re fine for their intentions. The majority of these companies are only applying these generic maps anyway

Everyone cries about EGRs but they heat the block faster and reduce emissions.  They can clog if poodled about but I cleaned my E39 one around 20k ago and I had it off the other day (the other half thought it ran away) and it was spotless.  Literally just a wipe clean amount of black soot.

 

IMO they do more good than harm so I'd never map it out.  People that have problems with them are on poorly maintained examples.
