I use the Bridgestone weather control A005 my car came with the geolanders which were junked within a week horrible tyres feels like its on slippery surface as soon as it rains, have also used the Michelin climate control on my 4x4 skoda
small local journeys cause this sadly the diesel boxer is designed for longer journeys only, the error is caused by the system assuming the oil is ash contaminated give it a good blast once a week down an A or Mway road should stop it
Petrol or Diesel?
Petrol ignition breaking down or dirty fuel filter the bang will be a backfire not good for the exhaust or cats etc
Diesel 100% blocked filter of water in the filter cuts off the fuel flow sounds like a petrol at rev limiter
Either way sort it or it will cost much much more
