This quite an undertaking! I am reminded (by your intention to make chopper circuits) of very dated technology such as controllers made by EVP, and the later Cableform Mk 10 boards. A chopper circuit system would require a pulse generator / on/off thyristers / commutation capacitors / Motor diode protection. Also a foot control suitably calibrated to suit the low and high on/off charactoristics of the circuit. I am a little behind the times now, BUT, a conventional chopper system was usually joined with lead acid battery as power source. In the past vehicles had 24v - up to 80v supplies, ranging from 200A/h (at the 5 hour rate) up to 500a/h (at the 5 hour rate) This related to road mileage was 15 to 30 miles max. Costs today would be prohibitive. Overall vehicle control would not meet an acceptable standard. To buy ready assembled components would introduce a greater safety element. Without being over negative - is such an expense justified on a fabia? In addition to the foregoing, there is the matter of transmission - again a potentially expensive move. I will look with interest at the post unearthed by George (earlier post). PS - recently tried a new Nissan Leaf, and was quite impressed by its performance C

Very risky - take time to have a comprehensive look through this forum. Full service history + new mot is meaningless! Sorry to rain on your parade.

Too risky - dont buy it!

Last thing you want are Break updates !!😀 What you want are Brake updates. Sorry, could not resist correction - but no offence intended.

Have you had a Skoda analyser test done?

marfrohun said - "Generally just try and keep it in the lowest gear possible " ?????? er Pardon, I think he means the highest gear possible, or have I missed something here?

Hello there the noise is appalling! - I suspect that you have recorded the noise from a very close proximity - that clouds the issue. First observations are as follows... 1 - The noise overall sounds very top ended, IE the valve gear is very noisy (possibly the closeness of the recording emphasises this.) 2 - The big concern is that when the clunk happens, it is almost like there is a full mechanical stop/lock taking place causing almost a stall situation, that just recovers due to the momentum of the engine - hence the movement in the engine within the frame. 3 - This is a curious one in that it is just possible that a momentary ignition failure happens with an almost instant recovery. I would be very concerned at the serious mechanical CLUNK which would make me immediately look at the chain/tensioner situation as a first action. Fuel filter and software is not going to overcome this problem. Please let us know the mileage of this car, and what repair work has been done that you know of. Finally I am appalled that Skoda (supposedly ) trained staff have been (it seems) unable to give you a definitive opinion/answer. Keep us in the picture, and I honestly would not be driving your car until it is sorted..

Cannot find your recording - message says not available!

Sadly many motorists seem to be unaware of the audible signs of chain stretch/ and shortcomings of the tensioner system, and blissfully drive on until one day - failure! There have (I believe) been two/three modifications made to the chain and surround items. People have had the earlier modification, and assumed they are now 'safe' - unaware that the original mod was superseded by those that followed. The dealers themselves were somewhat confused by the changes, and part number changes. The result is that many 1.2 TSI's are still possible victims of impending failure.

Comprehensive info on the forum re VRS, make time to read. Best advice? - other makes and models are available!

Assuming the new hub/bearing were fitted correctly - I suspect you have 'run out' on one of the disk.

Hopefully now you will see the point I was making (this is not a 'I told you so') comment. The expected result that you listed was a little ambitious perhaps. Having reached 85K, you have done well - if running well, leave it until you meet trouble.

Why do this? What do you feel it will achieve? Accept that this is not sarcasm, just a friendly enquiry. In reality the result will be hardly noticeable (if at all) - and the risk of not clearing displaced carbon fully, is a risk not worth taking. I would agree however that the use of chemical cleaners is a no no.

Please everyone - lets kick the idea that glazed pads cause overactive brakes - quite the reverse. To suggest this is very misleading and does nothing to give credibility to this forum. The one question that must be asked first and answered is this. As the car is Auto, is the OP left foot braking?

Good point, could avoid some nasty expenditure.
