2011Mini Cooper

Into our workshop was this Mini which had been recovered from another garage (BMW specialist) which had failed to fix the car after having it over 2 months!!

The problem with the car was ABS, traction light on and the steering lock inoperative. The previous garage as can be seen have tried fitting a new cas unit and then apparently 3 more(there were a total of 5cas units in vehicle)!!

The fault codes show faults in CAS and ABS modules. We coded in both modules correctly, this still left speed signal faults.

In live data the CAS unit thought car was moving even when stationary. That is why steering lock was not operating.

The CAS unit we know can think this if there is a wiring issue between itself and the ABS module. So examining wiring diagrams we can trace the loom and a broken wirer was found. A simple repair and the customer had car back the next day.

Hyundai i20 no heated rear screen

This vehicle came to us with a problem with the heated rear screen inoperative.

A look at the wiring diagram shows its more complicated than people would think.

When you push the switch it sends signal to chassis ecu, which then sends signal to fuse box and relay, which in turn sends signal to screen and engine ecu (which can raise revs slightly to help with the extra load the screen has).

The circuit tested it was found that the signal was being seen by the chassis ecu but it was not sending signal on. The rest of the circuit was checked in case of further faults, none were found.

A new module was sourced and fitted with confidence.

A first time fix with no parts cannon fired at it.

 

Mercedes horsebox

This old Mercedes horsebox came to us after it had a fire. An attempt to repair the loom had been tried elsewhere.

We decided a repair wasn’t feasible so we managed to source a complete vehicle harness.

After removing the old damaged loom and most of the interior the replacement loom was fitted, a time consuming job but worth the effort.

Radio Coding

Coding this set requires you to program the chassis number into the set

We have the equipment to be able to do this in house.

Rover 75 immobiliser fault

This car was towed into our workshop, the customer saying that they just came out one day and it failed to start.

Plugging in our diagnostic equipment brought up codes for immobiliser.

This car is based on a BMW e39 and knowing BMW quite well we were aware of communication issues between the dde (engine ecu) and the ews (immobiliser module).

We gained access to the module and were able to perform a coding of the module with specialist equipment.

The car started instantly and ran fine.

Peugeot non runner

Peugeot 206 came in from another garage. The original fault was wipers and left indicator on all the time. They fitted 2nd hand bsi which cured the faults but the car wouldn’t start because the bsi is part of the immobiliser system. So we were asked if we could help.

With the correct information and equipment we are able to swop the microprocessor containing the information from the original bsi to the 2nd hand unit

Not a simple task as you mustn’t damage the circuit board when unsoldering and reattaching chips and not shorting out the connections.

Another successful job perhaps saving a car from the breakers yard.

Hybrid Lexus

This hybrid Lexus was in our workshop to have a front camera fitted.

A neat professional and safe  job done. Another happy customer.

 

Hyundai wiring fault

 into our workshop was this Hyundai for a wiring fault. The fault was traced to behind the dashboard. As you can see here there is quite a bit of dismantling to gain access to the loom.

Mercedes SLK350 Parking sensors

Audi TT

This Audi was towed in as a non runner,the customer saying he thought it was a immobiliser problem. We checked for spark, that was OK. We checked fuel at the rail OK. We checked compression and air, again both OK. So if all things needed to fire are present was it timing? As we checked the fuel it didn’t seem quite right. We decanted some and found this

Water in the fuel. Next we had to find out why it was there. Bad fuel from a station? Leaking fuel system? After talking to the customer he said it had been laid up for months and on examining the fuel cap which on these cars is on top of the wing if had water damage in it

So we powered up the fuel pump to drain the system, ran some fresh fuel through and drained again, fitted new filter. Finally filled her up and ran the engine.
