Title: GTI Limp mode 4k rpm msg and far too hot (guage)
Post by: ajmoir36 on 19 November 2020, 08:47
So my sister called and said just while whe was parking up she got a message that said that the car exceeded 6000rpm and the temp guage went right up, EPC light and Orange triangle on dash. Coolant tank is good. I will be scanning the car later to find out. Ideas?

15 plate GTI (DSG) 220bhp

Hard to say it seems, but a quick google of similar errors on VAG vehicles suggests its basically one or more of the elements which control the combustion cycle having gone crazy. Could be a stuck inlet actuator or could be the fuel pump gone nuts.

Just be glad it didn't happen while it was in gear...

People seem to suggest its usually a transient problem, but does seem to reoccur after clearing down the errors.

Job for the mechanics I think.

I dont think it actually revved just a message.

Seems strange that the temp gauge shot up as well as the rev warning though?

I can't imagine the two things could happen unrelated?

Are you sure she didn't actually just stick her foot on the pedal accidentally while in neutral then?

Not yet, she is at work, will find out more when I scan it after 16:00 today. I am hoping its nothing bad and just a sensor I assume the water pump is not driven by the chain?

No it didnt rev wildly. She said it did a message and temp guage.

That explains the temp gauge but not the rev warning?

Post by: ajmoir36 on 19 November 2020, 19:54
The rev warning is don’t drive it above 4000 like limp mode, I assume it’s water pump/ thermostat that needs replaced.
Title: Re: GTI Exceed 6000rpm msg and far too hot (guage)
Post by: fredgroves on 19 November 2020, 20:08
Ahhh OK, initially you thought it said rev limit exceeded.

The limp mode makes sense.

Water pump problems plague these it seems.

Post by: ajmoir36 on 19 November 2020, 20:21
Yeah figured so looks like it’s a fairly hefty bill if you need thermostat housing and water pump. £1k ish from VW

Interesting is the tempature guage supposed to read 55 degrees when the car has not been used and just turned the ignition on, usually needle just sits on the stop?, i.e. water temp must be 16 degrees, as it has not been run since yesterday. Would this point to more of a radiator temp probe issue?

Car is in with an Independant today, fingers crossed it doesn't get too pricey before Christmas

Supposedly thermostat is stuck closed, new housing required and pump.

£654 at the independant place using genuine parts, VW wanted £1050. Although rang late yesterday to say the pump is on back order.

Post by: fredgroves on 27 November 2020, 09:18
Thats not bad, the part is about 400 quid I think... and its probably going to take 3-4 hours to fit.

Sounds about right - so VW main dealer prices are about 150 an hour for labour, your local indy garage its 50.

When you break it down like this, you can see how these bills skyrocket...

Aren't VW dealers supposed to price match local specialists using genuine OEM parts?

I would have thought so but that would involve getting a nice independant to write it all down in a quote then taking it to VW? Seems a bit harsh on the independant and so might as well give the business to the independant anyway.

Who would do the better job? thats probably depends on the dealer and the independant garage. Its all mechanical parts that need replacing. If only they didnt build cars out of chocolate these days and built them to last.
