Front Assist Not Available: What It Means and How to Fix It
'Front Assist not available' shows on Volkswagen, Audi, SEAT and Škoda. It's the warning that your car's automatic emergency braking has gone offline. Sometimes it's a dirty sensor and a quick clean. Sometimes the radar needs recalibrating. This page covers what it means, what to try yourself, and when it's a workshop job; calibration, when you need it, is priced per system from £162 inc VAT.
Before driving with a warning
Do not rely on the affected assistance feature. Follow the warning instructions in your handbook. If you are unsure about the vehicle's condition or whether to drive, get advice from a qualified repairer before travelling.
What Front Assist unavailable means
Front Assist is a name used for forward-collision warning and braking assistance on relevant Volkswagen Group vehicles. The fitted sensors and available functions depend on the model and equipment. Camera and radar information can be used together.
An unavailable message means you should not rely on the affected feature. It does not identify the faulty part or establish that the rest of the vehicle is safe to drive. Obstruction, installation, electrical faults and calibration requirements are different possibilities.
Include any accompanying ACC warning and recent work. Low voltage can produce fault information, but a flat battery does not by itself prove that the radar lost its calibration reference.
Make-specific guides
Volkswagen and Audi have their own Front Assist guides below. SEAT and Škoda dashboards usually pair this warning with 'ACC deactivated', and those guides cover the same front radar. Everything else on this page applies to every VW Group car.

Before you enquire
- 1
Read the exact warning
Follow the warning instructions in your handbook. Photograph the message while safely parked and include any other warnings. Do not rely on an affected assistance feature.
- 2
Describe recent work
Include glass, bumper, suspension, electrical or replacement-part work, and when the warning began. Missing details do not prevent an enquiry.
- 3
Keep earlier findings
Send relevant scan, repair and calibration reports. Do not repeatedly clear codes or test the system by deliberately triggering its warnings.
- 4
Explain practical concerns
Include your location and any unfinished repairs or concerns about driving. Seek qualified advice before travelling if you are unsure whether the car is safe to drive.
Which work may be needed
Front Assist can use camera and radar information, depending on the car. Include the exact warning and whether it followed glass, bumper, electrical or replacement-part work. A battery event does not establish that a calibration reference was erased.
A diagnostic scan reads available fault information. Its findings, repair instructions and any physical checks guide the next step; further investigation may be needed. The centre pre-scan price is £54 including VAT when that operation is required.
Front-radar calibration is £162 including VAT at a centre. Replacement configuration is a separate operation, listed at £232.80 including VAT. It is not a replacement-and-calibration package, does not supply or fit a part, and is not automatically required again if the installer has already completed it.
The vehicle-specific method can involve static work, a prescribed driving procedure or both. Calibration cannot repair damaged hardware, wiring or an unsuitable installation. The quote covers the work identified for your car; unsuccessful work or a return visit may carry charges.
ADAS calibration prices
Whatever badge is on the nose, the quote is per system: usually the front radar, or the front camera when the windscreen side set the warning off. Rates are the same at every service centre, per system, shown inc VAT with the net figure alongside. Your total is confirmed in writing before anything is booked.
Calibration — per system
Coding a replaced part to your vehicle
- When your job needs a diagnostic pre-scan, it's £54 inc VAT (£45 +VAT), itemised separately. It reads available fault information; finding the cause may require further investigation. A post-scan is a separate operation.
- Two or more systems in one visit: the highest-priced system is full price, each additional system is 35% off at a centre. Scans aren't part of the discount. Front camera and front radar together come to £267.30 inc VAT (£222.75 +VAT).
- Replacement configuration and calibration are different operations. The work required depends on the vehicle and what the installer has already completed. Configuration prices do not include supplying or fitting a replacement part, or an automatic calibration bundle.
- Unsuccessful work, further investigation or a return visit may carry charges, including at a service centre. The appointment terms and written quote set out the work and applicable charges before booking.
- Mobile calibration is available for garages and bodyshops with workshop conditions. Ask us.
Frequently asked questions
On any car showing this warning the job is priced per system, not per fault. Front camera calibration is £162 inc VAT (£135 +VAT), front radar is the same, with the full rate card on this page. Two or more systems in one visit: the highest-priced system is full price and each additional system is 35% off at a centre. Your quote is confirmed in writing before anything is booked. A diagnostic scan, when your job needs one, is priced and itemised separately.
Clearing a code removes a stored entry, not the condition that caused it. A returning warning can involve alignment, installation, wiring, hardware or another fault. It does not prove the radar needs calibration. Keep the earlier scan and describe when the message returned.
Send the previous result and explain whether the procedure failed, the warning never cleared or it returned later. Include any intervening repairs. A scan and further checks may be needed, but neither a warning nor a code alone establishes why the earlier work did not resolve it.
Yes, it's common. Plenty of good independent garages can do the mechanical repair but don't own ADAS calibration equipment, which is a separate, specialised setup. That's the gap our network fills. The repair garage does the bodywork or the part, and a calibration centre realigns the radar afterwards. You don't need a main dealer for either. The calibration side is priced per system, from £162 inc VAT (£135 +VAT).
Possible causes include restricted sensor visibility, installation or electrical faults, and calibration requirements after relevant work. Equipment varies by vehicle. Include bumper, grille, windscreen, battery and replacement-part history; no single trigger proves which operation is required.
Low voltage can leave fault information, but it does not establish that the radar lost its calibration reference. Include when the battery problem occurred and which warnings remain. A scan can inform investigation; repeated resets or calibration should not be assumed to be the answer.
The exact warning and vehicle condition matter. An MOT result cannot be predicted from the assistance message alone; the current DVSA inspection manual covers applicable braking and steering defects. Do not treat an MOT pass as proof of completed calibration. Insurance authorisation and documentation depend on your policy and repair; a calibration record is not a guarantee of claim acceptance.
