Volkswagen ADAS Calibration. Prices from £199. Anywhere in the UK.

Because a battery change on the Mk7 and Mk8 Golf can drop the front radar into a calibration-pending state, even though nothing physical was disturbed. A Golf owner came to us with that exact dashboard text after a battery replacement, and another whose front radar started reporting 'misaligned' after a new battery went in.

The VAG architecture logs the radar's last-known calibration reference. A full power-down during a battery swap can clear that reference on some firmware versions, so the radar flags because the reference is missing, not because the aim is wrong. ACC and Front Assist both run off the same radar. Fix: a recalibration sweep through VAG-compatible tooling. Fixed at £349.

C110300 on the Golf is 'cruise control sensor misadjusted.' A Golf owner came to us with that code after replacing both steering wheel buttons and coding the slip ring and cruise control. The diagnostic read 'Can not calibrate radar sensor as vertical angle is too far out of tolerance.'

The code doesn't mean the buttons caused it. C110300 is the radar reporting its vertical aim is past the angle the static routine can pull it back to. The trigger is almost always a separate event (parking knock, kerb strike, bumper repair) that's gone unnoticed. Fix: physical inspection of the radar bracket through VAG-compatible diagnostics. Bent bracket needs replacing; within tolerance gets a manual vertical aim adjustment and static calibration.

Because the J428 module on the Touareg CR is the adaptive cruise control slave that feeds both ACC and Front Assist, so replacing it puts both into a 'requires calibration' state until the new module is paired and aimed. A Touareg owner came to us with the exact J428 question, and another whose J428 had been replaced and was waiting on calibration.

The Touareg CR (2018 onwards) routes both the cruise side and emergency braking through the J428. A new module arrives with no calibration reference and no VIN pairing. Fix runs through VAG-compatible tooling in two steps in one booking: component protection clear and VIN pairing, then static aim. Our network handles the protection side. Fixed price applies.

Yes. A Transporter owner came to us with this exact problem: windscreen replacement booked, glass company refused the calibration because the vehicle had been lowered. Most windscreen-fitter ADAS rigs are set up for stock ride heights, and a lowered T6 or T6.1 sits at a different camera angle to the calibration board.

The windscreen camera runs Lane Assist and feeds Front Assist. When ride height is non-standard, the static aim needs the target board adjusted, or it writes a wrong aim reference. Our accredited workshops carry the procedure for non-standard ride heights through VAG-compatible diagnostics: measure actual height at the front axle, adjust target-board geometry, run static calibration. Fixed at £199.

Yes. We hear from Polo Mk6 owners regularly with this exact pattern: gloss black or aftermarket badges on the front grille, Front Assist warning within a few drives, bumper itself untouched. The radar transmits straight through the badge area on the Polo Mk6 front grille.

A genuine VW badge has known dielectric properties the radar's calibration accounts for. Gloss black, matte black, carbon-effect or aftermarket badges read as signal attenuation or a phantom obstruction. The system flags 'Front Assist not available' because it can't trust the radar's view. Fix depends on what you want to keep. Recalibration sometimes works if interference is borderline, but the reliable fix is refitting original VW badges and recalibrating through VAG-compatible tooling.
