Dear Team,

Now, from what I understand, the Fuel Pressure Regulator Valve (N276) needs to be replaced, which would take care of the knock sensor value etc.

The dealer says that the ECU needs to be replaced, and has quoted

1) engine control unit (ecu) 215917/ + Tax & labour charges will be additional.

I find that extremely high and I'm not sure whether that's the right thing to do. Advice on how to proceed now would be much appreciated. Is there a number at Skoda that I can contact? Is there an independent who would be able to handle this? Should I move the car from one authorised dealer to another authorised dealer and see what they have to say? Or is the diagnosis correct, and I should go ahead with the new ECU?

Any advice/help would be much appreciated.

Which dealer is it at right now? I see that only the throttle valve controller has malfunctioned, while the rest are intermittent faults. It might be only that which needs to be replaced. Either way can give you someones contact at Autobahn if you would like.

Try another dealer, also I am guessing you checked the battery voltages already, in which case you may want to check the MAF sensor before trying to change the full throttle body?

It's at JMD.

Would love to have someone's contact at Autobahn. I've heard JMD is the lesser of the two evils, but I wouldn't mind getting the car towed to Autobahn if I feel the person who I speak to knows what he's doing. Unfortunately I dont think that is the case with JMD right now.

I feel the same way too, I really doubt this translates to an ECU replacement.

When I look up some of the codes I get some different answers:

http://dtcsearch.planetvag.com/

Your code 01542 shows up on the above link as something with the throttle valve potentiometer. As you have a code 01545 that also points to the throttle valv controller I suggest you investigate this.

Just because you get a code like p2294 on the fuel pressure regulator, doesnt mean rip and replace will solve the problem. You would still need to investigate around the fuel pressure regulator. Could be as simple as a loose connection maybe.

I would take the car to a dealer and have it hooked up to a proper car specific OBD analyser that can read the generic and car specific codes, preferabley the VAG codes. Then let them show you the meaning in the workshop manual, because it will also for each code show what to do next, i.e. what to look for what to test, what to replace etc.

MIght all be built into the scanning device the dealer is using, if not the information will be in the workshop manual.

You could also try one of the Skoda specific forums. Go for one in Europe as lots of their owners will be doing work on their cars themselves.

Good luck

I searched P0606 on that same website under OBD2 and it showed me


16990 P0606 ECM/PCM Processor

Still doesn't mean it needs replacing. needs further investigation. Here another website that does a reasonable job of listing various options what could cause this code and thus what action to take:

Replacing the computer is really the last resort when all the other probable causes have been ruled out. Generally speaking its very rare for the Computers to go faulty. Its nearly always something else.

If I was to take a go at your engine I would try and fix all the other issues and codes first. The. Reset the computers and see what happens.

True. And even before doing that, giving this guy a shot might be worth it.

Replacing the fuel pressure valve will not set right the knock sensor values.

It is the fact that you have 5 error codes at one time which requires quite a bit of analysis by the ASS that has prompted them to attempt the easy way out by suggesting a replacement of the ECU.

The sad part is given the error codes you have, a replacement of the ECU will not solve all issues. Which means that after you replace the ECU, they will tell you to replace more stuff.

As indicated you need to go to a competent VW workshop that can do a proper analysis as indicated in the workshop manual – there are quite a few competent VW FNG’s that are coming up these days (don’t know if there are any in Mumbai) and it might do well to take your car to them as ASS’s these days don’t have the time, patience, competence or inclination to take complex issues to their logical solution and hence attempt these short cuts.

Dear Holysmoke,

How did you manage to solve the starting issue for your Škoda Superb?
Was the ECU replaced / repaired ? Or was there any other issue found ?
I face now a very similar challenge with my Škoda Laura.

Thanks!
