Hi All, 

What tools would I need to remove the ECU - I have a 2010 fabia vrs. The car broke down so its about 30 miles from me so I need to take some tools to remove it, cant find anything about removal on internet. I have enclosed the RAC report after ringing round etc ... they all seem to say it is ECU failure. Drove to work fine no issues haven't had any issue since getting the car not lights or faults popping up nothing. got in it and it wouldn't turnover fault on dash saying ESP that was it.

 

Thanks,

 

Tony.

Not much in security bolts stopping the ECU being removed with your ECU from 2010.

 

Do not touch it though.   What is actually really wrong? 

 

I can not open the link for the report.

 

Your Twincharger might not have the engine now it left the factory with or the ECU it did.

 

Look at the little orange sticker on the drivers side of the engine and the one on the ECU, are they the same 4 figure number.

Is the date still readable. 

 

Maybe take a picture of the ECU and the Barcode on it.   Is there a orange sticker on as well with the 4 digit number?

@TonyNew Once you have the ECU removed where or who are you taking it to?

ECU failure is extremely rare and a new one is not plug and go, start by getting the car somewhere a fault code read can be carried out and post the result.

@TonyNew & are you sure it was not the EPC light / Letters,  not ESP?

Hi,

 

I'm not near the car, I had to leave it outside work, it is stuvk in park and we have off street parking so couldn't garauntee a spot for them to drop car.

I'll look when I go back up on Sunday.

I was going to send it off to be repaired - the dash said Fault: EPS it wasn't epc  but yeah all dash lights were on but couldn't start it so not sure what would have gone out. This is the general text from the RAC report.

So to remove it is just clip out??

 

Thanks

 

Tony

Your OP says it said ESP.  I take it that was a typo you just posted.  

 

Really do not remove it yet. 

The plug can be a cause of issues.   As to sending for repair.   Who is it going to?  

 

@Crasher is a Technician -mechanic.  Best placed to assist maybe.   Or tell us approx where the car is, there are others here that know the cars.

The battery or battery connection, earth might be the simple explanation.  But then the RAC Operative checked that did they, not just plugged in read codes and left it at that? 

 

Like the one that came out to my Electric Corsa, cleared the codes and said sorted.  I said close the door and move the car please.

Later that day and after hassle it went on the Recovery Truck with the Rear Wheels locked and the front locked due to the failure not diagnosed. 

 

eg.

Yeah that was me it was definitely EPS that came up on dash.  The car is in Surbiton Surrey KT5 at work normally in Crawley West Sussex.  I haven't decided on whop to send to after speaking to them that wanted part numbers etc which didn't have so was going to remove and call Monday. In the running though is a company call ECU Testing or AC Tronics

 

 

Yeah did the battery test first when he saw the fault immediately said battery but that checked out fine,

@Crasher the RAC bloke said most of his calls are down to faulty ECU's said its a common issue for them to packup all the time???

My issue is, there is not a EPS light i know of on a Mk2 Fabia vRS from 2010 - 2014.

 

My issue is RAC people talking sh!te.   

 

Look in this section from 2010-2024 a see just how many ECU failures there have been.

Lots of Mk2 vRS owners and cars have been here in the 14 years.   There are less than 3,000 of the cars in the UK.

Then the Audi, VW & Seat Twinchargers.   ECU failure very rare.

 

There were 3 outer cover ECU,s 2009-2012, then 2 different after that.

Locked ones, and ones with security bolts and ones without.     We had to open to remap.  Some were wrecked or cooked by idiots.

Jackanory, Jackanory...

I have been a VAG mechanic for 42 years, in that time I think I have replaced less than 100 ECU's and most of those have been EDC 16 and 17 Diesel units suffering from water damage BUT there is always a first time.

 

Your car is actually a 2011 model year and the ECU 03C 906 027 CE retails at £1182.60 inc. VAT BUT there is no UK stock and it is likely to go obsolete if ordered.

Edited 12 April, 20242 yr by Crasher

Did the RAC manage actually try a new battery on it or just test it as the issues sounds very much like those I had years ago when my battery gave up.

 

Drove fine, parked up, locked car all ok.  Came back, unlocked and tried to start but nothing other than a dashboard full of warning lights and faults.  A new battery sorted it.

So it wasn't a light on the dash it came up in the center info panel   Fault EPS I'll take a picture on Sunday

 

So can these ECU's be repaired??  Also if it's not the ECU what could have gone to cause all the error codes and the not to start or even turn over?

 

Like I said I have had the car 15 months and never had a light or fault flick up on the dash except the tyre pressure light??

the battery tested fine its in the notes further up the page?

Ignition coming on and then not turning over with a Mk2 Fabia vRS can sometimes be an issue with the DSG shifter not fully in P.

The car can also start in N, so when it moves out of P worth trying in N. 

 

Sorry, i missed where you said you had it 15 months.

 

Another issue has been a water ingress one at a connection, sometimes at the Water Pump area and usually with a Water Pump needing replaced.

That is also the Super Charger clutch which is when a EPC light sometimes comes up.

Yes I know that hence my question as that is exactly the problem I had.  Battery appeared ok but wasn't when actually put to use trying to turn the engine over...

You can't move the shifter it is like its locked in P tried to move it to neutral but wouldn't shift

 

That is an issue.

There is in the owners manual the instructions for getting it out of P if it gets locked in.

 

There might lay your problem. 

 

There are threads on how to get it out of Park & youtube vids, and obviously a RAC responder knows as well, they will be seeing that issue lots as well.....

Edited 12 April, 20242 yr by Rooted

Yeah found that in the owners manual - if I can get it into neutral I'll be able to get it recovered home which will make it a bit easier for me to do some research and try out some of your suggestions.

 

Back to the battery he also had a battery pack on the battery so would this have corrected a low voltage if that what was causing the issue.

 

Do I leave it as it is and just get an auto electrician to check and tell me what the issue is, just trying to save time and money.

 

The ECU seemed a simple fix and the the option that made the most sense to me, is it worth risking the cost of a battery never had any issues with it or having troubles starting etc??

 

The only other thing i can think of is I fitted a dashcam hard wired into the fuse box using the dual fuse holders to plug in it has been in the car for over 6 weeks now but could that be causing an issue I made sure i stayed away from crucial fuses can't remember what I used now.

 

It was an asdome M300s and the JYX04 hardwire kit??

@Crasher what battery do you recommend - I have search on google but a range of batteries are coming up for my reg from 50amps to 70 amps I assume the 70 is best

DSG /   Do not tow it with the front wheels on the road.

 

Get the battery that it shows on the battery test.
