[P046C - EGR Fault]

I have the above fault appearing pretty much every drive on my 1.6CR Tdi. It can occur 1 minute or 1 hour into a drive and is always accompanied by the glow plug warning light and sometimes the engine management light. The car goes into limp home mode until i next start the engine where everything functions as normal. 

 

The car is booked into a diagnostic with the garage i bought it from (only 5 month old) on monday but i need to drive approx 50 miles each day until then. At the moment im having to use Torque on my phone to delete the faults any time i need the acceleration (merging into an A road etc) but the rest im taking easy. 

 

Im considering taking it for an italian tune up, does anyone advise for or against this with this particular engine? 

I have a similar issue with a CAYC engined Fabia 2. Now my engine warning light is on all the time and I have also started to get the DPF light. I have it scanned a couple of times. EGR seems to be the main issue but DPF also has 28 grams of ash which a mechanic told me is high, although it does not seem that bad to me. What was the result of your scan?

Has anyone any experience of cleaning an egr on a Fabia 2 with the CAYC engine? Could do with some advice about how to get it off.

Slightly off topic but I have P046C and P0407 fault codes on my CAYC engined Fabia 2 (1.6TDI 90HP). Has anyone cleaned an EGR on one of these? I understand they are a tad difficult to get off as they are connected to DPF etc.

I'm not an expert on this subject but the usual options are either clean EGR, replace it or buy a blanking kit to eliminate it preventing further issues!

Thanks for reply, do you know anyone who has used Wynn's EGR cleaner? Does it work?

[P046C & P0407 Faults]

Hi, I keep getting these fault codes when my 2010 Fabia 1.6.TDI 90hp is scanned on VCDS. These look like EGR codes and it looks like a need a new valve. This is expensive and I would obviously prepare a cheaper option, does anyone think it could be something else or is there something I could do short of replacing the EGR? Also my DPF has 28grams ash, does this look OK? For information, the car has done 69,000.

I would be grateful for any advice.

Hi Trundle, I am only down the road off the A444. Can we arrange something for next week as I will be off?

[1.6TDi 105 -warning light "control system for exhaust" & flashing glowplug light]

Yes I have been using the motorway to get to work and back, I was recommended to try third gear for about 30 miles by a friend keeping it at 2500. I did this last Friday and lights stayed off. However, yesterday (had day off on Monday) I drove to work again on motorway and coil light came on again after about 30 minutes of high rev driving. Thereafter, on the way home last night, it stayed off until I was almost back. It only came on when I had to reduce revs as I was on an A road. This morning I have just driven into work and the coil has come on after about 2 miles, then the engine light came on and has stayed on! Anyone know of anyone with a VCDS in the Derby area who is around next week?

Dealer definitely said 28g of ash. He switched codes off with VCDS but glowplug light came back on the way back after about 10 miles of slow traffic. No others have come back on as yet. I had it MOTd yesterday and I asked the guy to put it on his system to check. No warning lights were on at the time and he could not find a fault. He also said that he had tried to regen but he could not and he thought this was because it was registering as very low in dpf. He said he used Snap-on but that he had up to date VWG codes.  However, this morning I drove to work and the glowplug light came on after about 20 miles of motorway driving. It did not go into limp mode. Any ideas?

Have now had it on scanner. It came up with EGR, EGT and pressure sensor faults. It also registered 28 grams ash in DPF. Does this sound a lot? Is it terminal? Looks like it will cost 1000 to fix!

Hi 2ndskoda,

 

The brake lights are still working, only the tail lights have gone. I heard that the brake lights  could cause problems, especially on the Mark 1. Do the tail lights have the same effect?

[1.6TDi 105 -warning light "control system for exhaust" & flashing glowplug light]

Hi, I am new to the Forum and very worried. I have had similar problems to those decribed with my 2010 Fabia 1.6 TDI. Glow plug flashing after some time driving, engine warning light on and recently dpf warning light. This morning I noticed that the tail lights were not working, I do not know if this is related.

 

I live in the Derby area, near Swadlincote. Does anyone own a code reader that they would be prepared to plug my car into? Alternatively, could anyone recommend an honest and reliable diagnostic service in this area?
