Glow Plug Symbol Flashing on Yeti 110

[eribaMotters]

If I am reading this thread correctly, the problem is when the engine is hot. Any reason why it could not be a glow plug problem?

Although not exactly the same problem, my previous car, a VW Touran was a very poor hot starter. After glow plug replacement at 65,000 all was fine.

My glow plug light came on and engine went into limp mode on the M5 New Years Eve. Skoda assist called he put his computer on, EGR valve failure told me it would cost £1,400; replaced under warranty had 10 days left on it.

How many miles had it done at the time?

That's why some fit the catch can - it reduces the fouling of the EGR.

Hi silver1011

 

Agree with you and if I can find somebody local around Norwich who would be willing to plug their VCDS for a small fee then It would at least let me know what has been recorded. I have a plug in reader for BMW motorcycles but at £270 for yet another one for Yeti's just to read out the fault codes is a little expensive unless the miss's keeps to Yetis long term.

Anybody around the Norwich area willing to plug into my Yeti 110? By the way I love the crazy position of the brake fluid plastic tank. Have to use a syringe and tubing just to safely fill it up having had all the brake pads out with 47,800 miles on the clock. Got a big surprise as there was plenty of brake material on all four sets of pads. Done another 150 miles and no faults popping up since the first glow plug symbol flashed up on the screen.

Back on the fault chaps with the Yeti in limp mode until the wife turned the engine off and let it cool down before driving off again with no more errors coming up on the dash.

 

A very helpful member offered his services to plug in my Yeti 110 and show me the read out from his laptop.

It came up with two faults as suggested 4891& 4892 EGR Valve malfunction. Intermittent not conformed. Yeti has now done 1,000 miles without any hint of the EGR valve.

 

A big thank you to rayf who lives just a mile away from my home in Norfolk. Not only did he show me how you plug in his reader but also handed over a memory stick with the faults recorded.

I will have to return his help in the future as he would not take a hand out for all his trouble or a bottle of something. Briskoda is a fantastic place to get advice and learn from others with the same brand of vehicle.

So a big thank you to all the offers from helpful members.

 

Will hopefully be able to return the favour in future years.

We had the glow plug light indication on our Yeti CR 110 (2010 build, 120,000 miles) about 6 weeks ago. Came on continuous initially. As said above, although this is suggested in the manual as an EGR indication, in practice (and as above) it is the last resort go to indicator for a whole myriad of other problems too. (Why the glow plug is used as "unidentified fault" I cannot fathom?)  A couple of days of commuting followed with no apparent further ill-effects.

 

The car was already booked in for diagnosis at the local independent specialist where we got the car from. The laptop there said a bunch of fault codes, only one of which was "possible EGR". All cleared.  None returned. So prognosis was "carry on - see if the fault comes back".  Two days later it did, when car was half way from Yorkshire to Cambridge. The light then started to flash, accompanied by the engine management light and semi limp mode. This only happened when engine hot. After a cool off period it would then start up with just the continuous glow plug light again and full performance.

 

Re-fuelled in Cambs (with Shell!) and within 5 miles, glow plug light extinguished and full performance was available. After a further stop, cool overnight and re-start, all lights were out. Did not return for the 3 hour journey back. Returning to the local Indie next day, laptop revealed two more historic codes in memory relating to fuel system, etc. All cleared at that time and nothing returned since. Diagnosis: "A batch of contaminated fuel". Tankful in question came from a local supermarket. Can't prove anything wrong with it as tank by then was full of Shell and car running perfectly. As it has continued to do in a little over 2000 miles since then.

 

Make of that what you will?  But until proven otherwise, I'm of the opinion there was not a lot wrong with the EGR?

Hi FlintstoneR1

 

Interesting reading your tale of problems because having quizzed the Miss's she normally fills up the tank in the city at Sainsbury's for the last four years since we bought the Yeti from new. (2011 taxed, 48,000 miles) Now when the problem occurred she filled up at a little village petrol station in Suffolk as the tank was getting low and the fault occurred that day. After a couple of long runs and another full tank from our usual place and a trip up to Skelton in North Yorks to see relatives no more problems have appeared with the engine management system. 

 

Like you without taking a sample of fuel and persuading somebody to check it out I have no proof as I no longer have the facilities in a lab to check flash point, water content etc. So have cleared the fault down with member rayf's laptop and put in my log book for a rainy day. Told the Miss's not to use a little run down petrol station that may not get through large quantity's of diesel fuel just in case.

 

Thanks for that information as I did not think of quizzing the wife where she filled up when the glow plug symbol popped up and put the engine in crawl mode for some 55 miles getting home to Norwich.

I was given the same diagnosis - cr*p fuel by a French recovery guy last year, his view could have been water droplets - who knows, it cleared itself , using total excellium now!

[FlintstoneR1]

I will add that we normally use either Sainsbury's or Shell, and that the outlet where the tankful of supposed dodgy fuel came from was NOT either of those! Nor the most local Morrisons.  

 

Are these CR engines or common rail systems generally more susceptible to either higher than normal biofuel content in the mix, and/or water contamination?  I can understand getting water into the fuel in the scenario you mention of the rural filling station. Where the holding tank perhaps spends long periods half full, so more opportunity for condensation inside the walls.   That used to happen in the farm scenario, using above ground holding tanks for tractor fuel. Modern on farm drawing off systems have water traps for that very reason, as do tractor fuel systems themselves.  (Back in the day we used to draw off tractor diesel into 5-gallon cans, for transfer to the tractor. Can't imagine that happening now! Progress for the good there.)

Hi had same thing flashing glow plug light came on then limp mode code said egr valve bill £800 filled car with Shell V-Power Nitro+ Diesel plus redx then kept revs up to 3000 when I could. After 4 tanks no light revs at tickover went down to 750 when car was just starting to warm up. Cheaper than egr replacement .the thing with the revs started before the warning light so might be a early warning
