Front Assist is your VW's automatic emergency braking, and 'not available' means the radar or camera that runs it has stopped reading the road. Common on the Golf, Touareg and Passat. Here's what triggers it, and what the fix costs.
You can drive the car. Front Assist is the automatic emergency braking, and while it's unavailable it won't intervene if traffic stops sharply ahead. Normal brakes, steering and cruise all still work. Leave more following distance and treat the car as if the system isn't there until it's fixed.
Front Assist runs off a radar behind the front grille and a camera at the top of the windscreen. Anything that disturbs either one, or the coding that ties them together, can take it offline. Find the cause that matches your VW.
The radar that feeds Front Assist sits low behind the front grille. A bumper that's been taken off and refitted, or a new grille, rarely goes back at the exact angle the radar needs. The aim shifts, the readings stop adding up, and the car switches the safety system off.
Even a tidy front-end repair leaves the radar and camera needing realignment. The body shop sorts the panels and paint; the ADAS calibration is a separate job, and it's the step that often gets missed. Front Assist stays down until it's done.
Front Assist isn't radar alone. A camera at the top of the windscreen reads the road and backs up what the radar sees. Replace the windscreen without recalibrating that camera, and Front Assist drops out a few miles later. A smeared or misted camera does the same thing.
This one catches VW owners out. Fit a towbar, hardwire a dashcam, or have other electrical work done, and Front Assist depends on the car's coding being updated to match. Get the coding wrong and the system loses its basic settings. Fault code C110b54 points straight here, and we see it most on the Touareg.
Packed snow, road salt or thick grime over the radar behind the badge can be enough on its own. This is the cause you can rule out yourself: clean the badge area, restart the car, and see if Front Assist comes back before you book anything.
Some owners have already paid for a calibration and Front Assist still isn't back. Usually a hidden fault was missed, a bent bracket or a damaged radar, or the procedure didn't finish cleanly. A proper diagnostic scan finds which, before you pay twice.
Two codes come up on VWs with this warning. C110300 means the radar can't complete its calibration. C110b54 means a basic setting is missing, the one we see after towbar or wiring work. Neither means a dead radar. Both are calibration or coding jobs.
Worth a quick check first: clear any dirt or ice off the radar behind the front badge, wipe the inside of the windscreen by the camera, and restart the car. If 'Front Assist not available' is still showing, the system needs recalibrating, or recoding if a towbar was the trigger.
The fix is a fixed £349 through our network, with the diagnostic scan and a calibration certificate included. If the scan shows the radar or a module has failed, you'll know the cost before any work starts.
There's no charge for the diagnostic if you decide not to go ahead. See how ADAS calibration works for the full procedure.
Pricing is fixed across our network. Same price wherever you are in the UK. Your tier is set by what work has been done, not by your postcode or your car's make.
All prices include the diagnostic scan, the calibration procedure (static, dynamic, or both as required), a post-calibration check, and a calibration certificate. No charge for diagnostic if you decide not to proceed.

Yes. Front Assist relies on the car's coding being correct, and fitting a towbar or other electrical equipment means that coding has to be updated to match. If it's done wrong, the system loses its basic settings and switches off. Fault code C110b54 confirms it. The fix is a recode and, usually, a recalibration to put the system back.
On the Golf and Touareg, front-end work is the trigger we see most. A bumper that's been off for a repair, a refitted grille, or a collision repair all shift the radar's aim. A new windscreen does it through the camera side. On the Touareg specifically, towbar wiring is a common one. Most of these need a calibration, not a new part.
Radar calibration is a fixed £349 across our network, the same price wherever you are in the UK. That covers the diagnostic scan, the calibration, and a calibration certificate. If the scan shows the radar or a module has failed and needs replacing, you'll know the cost before any work goes ahead. No charge for the diagnostic if you decide not to proceed.
Almost always one. Front Assist and adaptive cruise control run off the same front radar, so when that radar loses its alignment, both systems drop out together. It looks like two faults on the dash but it's one cause, and a single calibration brings both back. You're not paying twice.
Front Assist, ACC and lane assist run off the same front sensors. If your VW is flagging more than one, a single calibration visit usually clears them together.
The cruise side of the same radar. Often offline at the same time.
