2022 VW Transporter in for latest software update on the engine control unit.

Vehicle was displaying an oil level high message on the dash and had already had the oil changed twice this year!

A Technical Service Bulletin relating to the vehicles current software number hit the nail on the head, giving the exact symptoms and fault codes.

Is your car feeling underpowered? Not thought much of it as no engine light to come with it?

A perfect example is this lovely little BMW 118D in today for a swirl flap delete.

Customer knew something was wrong as the car wasn’t at its best but no lights or warnings.

A diagnostic scan revealed that the swirl flap actuator was showing as faulty. After testing the motor and found it to be brown bread we gave the customer the options..

A quick remap on the engine ECU and removal of the flaps and the car now is now back to its former glory! 🙏

Just a snippet of 2 vehicles we had in last week.

None of which would have been possible without the latest dealer equipment.

One with an SOS error which was down to a faulty telematics module.
New module fitted, coded and programmed and no more error messages!

The other had no steering controls, traced down to water ingress in the gateway module. Bit shocking for a 2021 van but there you go!
New module fitted, coded and programmed and everything working as it should.

We can perform all of the functions that a main dealer can and are a fraction of the price!
