Loss of power, limited revs

[Auvache]

Hi guys,

I have a SEAT Ibiza FR 2011, 2.0 diesel. I am having issues with my EPC/glow plug light.

The light flashes and my car has a loss of power/restricted revs of around 2k. I can pull-over, restart the engine and the light disappears and power is restored. This has happened three times now and I am curious to know if my car actually has a fault.

It happened once, then I restarted the engine and it went away for over 2 weeks. Then today it happened twice within 5 minutes... runs fine after I restart my engine though.

I drive at least 60 miles a day on the motorway, half of the time spent in traffic. I have done around 33k miles.

Please help!

Thanks,
Brad

Based on the age of the car and the driving you said you do, I would get the battery checked and check the alternator first. The intermittent fault could be caused by a sudden power drop from a weak battery.

Does it happen in a particular scenario, similar weather or stop start traffic perhaps, or just random??

I am pretty sure that it is going into limp mode. I had a 2.0 tdi Altea that did exactly the same.
I cured it with an "Italian" driving session

It seems to be pretty random. It can happen in traffic or driving at 70mph.

you need to get it vcds scanned otherwise it's just guess work

I agree with Big Col on the scan, but get the battery checked first, most places will happily do it for free.

Also the fact that a restart can cure it sounds rather odd and it may not be picked up with a scan (I may be wrong). If the battery proves to be okay, get it scanned and see what comes up.

Ok so the diagnostics said it was an 'EGR valve fault', any idea what this could be?

My friend said these need to be cleaned regularly, do you guys think this could be the problem?

The EGR set up on the CR engine looks to be a bit of a nightmare.

See this thread from another forum. The dealer price for replacing it would be £700+. Over £300 for the part and then over 4 hours to replace it. ouch.

Yeah I've just had my emissions fault light come on as well. Local garage has quoted me £600-700 to replace the EGR.

Happy days.... -.-

You could try some Italian driving for a while and see if that helps, or some EGR cleaner. No idea how well they work as I have never used them.

Another alternative is having the valve blanked off, although I think you will need the DPF removed as well if you do this.

I wouldn't recommend egr cleaner the thickness of the carbon build up is so strong it doesn't always do a gpod job, if it limps again you can always switch your ignition on and off really quickly this will knock it out of limp mode and you should be alright for a little while longer but if I was you I'd go more down the route of egr delete and dpf delete better for the car more mgp, more power more reliable, but can be costly still.

A DPF delete will land you in hot water at MOT time

Only if they spot it, so long as it looks intact it will pass as it only requires a visual inspection for an MOT.
