Stop-Start Not Working — Tile Hill fleet jumpstart & Coding
Stop-start disabled or AGM battery failing in Tile Hill? Replacement requires battery registration to the BMS. Mobile fleet jumpstart with coding included.
AGM and EFB batteries handle far more charge cycles than a standard flooded unit, which is why manufacturers use them — and why they cost more and need proper handling when they fail.
Fleets working out of the CV4 area — courier, plumbing, electrical, HVAC, roofing, letting agents — call us daily. We know your vans, we know your yard, we know when your first drop is.
We invoice monthly with full PDF breakdown per vehicle — clean for accounts to file, VAT-compliant, no per-job card fiddling.
How start-stop failure shows up first
Drivers usually notice the stop-start light staying off for a week or two before any starting trouble appears in CV4.
Locally that means the streets between Tile Hill and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~4 mi) and Nuneaton (~9 mi).
Vehicles and owners affected
Owners of vehicles from roughly 2012 onward across Tile Hill — the vast majority now run start-stop.
Domestically, post-war estates and modern infill dominate around here, which shapes how these jobs are accessed and worked.

Stop-start gone quiet?
That warning is worth acting on. We test with an AGM profile and carry matched stock on the van. We route in via M6 J2/J3, roughly 4 miles out from Coventry.
Coding, sensors and correct chemistry
- AGM units are tested with an AGM-specific profile, because testing one as flooded lead-acid gives a falsely low reading.
- Memory is maintained during the swap where the vehicle needs it, so radio codes, seat positions and steering angle calibration survive.
- Priority dispatch for account customers — fleet jobs jump the domestic queue
- On a fleet jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.
AGM and start-stop questions
Q.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.
Q.Why has my stop-start stopped working?
The battery management system disables it when charge acceptance drops. It is a protective measure, and normally the earliest warning of an AGM battery reaching the end of its life.
Q.Can I fit a normal battery instead of an AGM one?
Not on a vehicle designed for AGM. The charging voltage and cycling regime will destroy a standard flooded battery quickly, and stop-start will stay disabled.
Q.Do you code the battery on-site during a fleet jumpstart?
Yes — registration is done in the van with the diagnostic tool before we leave, and we confirm the new profile has taken.
Q.Do you cover Tile Hill and the CV4 area for this?
Yes. Tile Hill is inside our routine coverage from Oldbury via M6 J2/J3, roughly 4 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.What if a driver is stranded outside our depot?
That's what account customers get priority for — one call from the driver, we handle it and bill your account, no card payment at the roadside.
AGM jobs completed nearby
Recent job nearby: a family SUV in Tile Hill with stop-start inactive for a month. AGM tested at 58% state of health, replaced and registered — stop-start active again on the test drive.
Recent job nearby: a car near M6 J2/J3 on its second battery in 14 months. The previous unit had never been coded, which explained the early failure.
Nearby areas covered
As a neighbourhood of Coventry, Tile Hill is covered alongside its parent town, so a start-stop and agm systems call from any of them routes to the same engineer.

The short version
AGM failure announces itself early through a disabled stop-start function. Testing with the correct profile and coding the replacement is the difference between four years of service and fourteen months. Either way you get the readings, the reasoning and a working vehicle before we leave.
