Hello John As I said on the phone I am sorry you have a running problem with your car and that it got worse after we had re-entered the injector codes as part of the diagnostic During diagnosis we scanned the fault codes there was an old code for fuel pressure, this cleared and did not return even after a road test. As we have seen unstable idle faults before often due to injector coding having been 'lost" by the Engine Control Unit ECU we then re-introduced the codes physically written on injectors (which were the same as the codes previously stored in the ECU) back into the ECU via the computer, after doing this the idle was stable. However during road test it appears that a more pronounced diesel knock became apparent. We then advised you that the fault was almost certainly with the injectors. As genuine Skoda Injectors are over £500 each we would need to send the injectors away to be tested and if necessary. I can appreciate that your car appears to have got worse after we worked on it, however there is nothing we physically did to cause this and my view is still that the defect was potentially there already. I have already offered as part of our complaint procedure to investigate further without additional charge, this in line with the Bosch code of conduct as approved by Trading Standards. Yours Tim B.

Didn't even show up on the diagnostic report. Also suggested it APPEARS to have got worse since they changed the codes.

It's a VW AUDI PORSCHE specialist with Bosch accreditation. Seems pretty clueless about what he's done as he's admitted they altered/re-set the codes based on their previous experience of the fault being caused by injectors on different cars.

Having a hard time getting the 'specialist' to admit fault. It was perfectly fine with slight pressure on the accelerator (still well below 1000rpm) and I was getting 70mpg +|-. Now i can't even drive it to the garage to get another diagnostic.

I Don know about the coding but they are the original injectors. I hope they put the correct codes in. Sounds like a tin of nails.

The judder got progressively worse. Bought the car in late January with no obvious juddering but after a few cross country drives the judder became pronounced and turned into the point where the entire engine was shaking on idle. Original injectors recoded by a VW Audi Bosch specialist (so they say). Asked about driving to Cardiff and Leicester from north west Wales and he said he doesn't recommend it. Paid £120 for the diagnostic and recoding. He said he couldn't put them back to how it was before but I wouldn't want it like that either.

Just had injectors recoded at VW AUDI specialist and instead of lumpy idle I now have diesel knock. Anyone tried liqui moly diesel purge with any success? 1.6 terrible damn idea.

Took it to VWAudi BOSCH specialist for diagnostic. Injectors needed recoding but this has caused diesel knock. Needs new ones apparently.

Mine makes the same noise. Runs fine when cool but idles lumpy when warm. Squeaky click coming from same part.

Need help diagnosing this. Cold idle is smooth. Warm idle is jumpy. Car drives great. Getting 70 mpg average on run from Cardiff to Bangor. If o apply slight touch to accelerator the lumpiness stops.

No need to be a kittens. Was simply asking about tyre sizes.

Winter sport 3D

Hello, trying to find out whether 185 65 15 will be suitable for my Fabia that has 195 55 15 tyres. Got a decent price on 4 Dunlop winter sport tyres.

Got a 'new' 1.6 the other day and almost immediately after I'd signed over and handed over the money I started the car and it was lumpy - didn't happen on the test drive. It's been ok for a couple of hundred miles and it's started again - I think it's a timing belt issue as it's due for a change. Any advice would be great.
