🔧 January Diagnostics Highlights at EAE 🔧

January kept us busy with some proper head-scratchers. Here’s a look at a few of the more challenging diagnostic jobs we tackled this month 👇

🚨 Mini Alarm Going Off?
This Mini came in with an alarm that wouldn’t behave. The cause?
➡️ Loss of communication between the siren and the roof module (the LIN Bus master control unit).

Further inspection revealed corrosion from water damage inside the roof module. Digging deeper, we found the real root cause — the A/C drain was leaking inside the vehicle, soaking the passenger-side carpet instead of draining outside.

💡 Fixing the water ingress before replacing the module was essential to prevent a very expensive repeat repair.

⚡ BMW E34 – Persistent Misfire & Burnt Coils
This E34 arrived from another garage with a permanent misfire on cylinder 2 and ignition coils failing after around 30 minutes of driving.

After extensive testing, we found a voltage drop on the coil signal wire — something not present on the other cylinders. Wiring checked out fine, so the ECU was opened up…

🔍 Inside, we discovered a failed capacitor within the engine ECU, confirmed with resistance testing.

Diagnosis complete — the challenge then became sourcing a replacement ECU for a vehicle where parts are now hard to come by.

⸻

🚶 BMW Z4 – Pedestrian Protection Warning
A Z4 came in from a dealer with a pedestrian protection warning displayed.

The fault was traced to a failed pedestrian protection pressure sensor behind the front bumper.
✔️ Sensor replaced
✔️ Fault cleared
✔️ System fully operational again

⸻

🛠️ Correct Diagnosis Saves Time, Money & Repeat Repairs
These jobs highlight why accurate diagnostics matter. If your vehicle has a warning light, fault, or something just doesn’t feel right — we’ll find the cause, not just the symptom.

Another stunning 997.2 rolled into the workshop last week—this time for a fresh back-box upgrade for .

We traced the unwanted noise to the right-hand box, where an internal baffle had almost certainly given up. Rather than refit a costly OEM unit, we opted for something far more exciting…

In went a premium stainless-steel sports system from :
🔥 Sharper, richer exhaust note
✨ Clean, purposeful styling
🔧 Zero rattles and a perfect fit

A proper upgrade that transforms both the sound and the presence of the car—exactly what a 997.2 deserves.

Last week we fitted a Milltek X-Pipe to this stunning Guards Red 997.2 GTS.

The goal? A louder, raspier exhaust note — and we’d say that’s been well and truly achieved 🔥

We also added front and rear cameras integrated with the aftermarket radio for a modern touch.

From servicing to performance and electrical upgrades — we do it all.

A few of the more unusual projects we’ve had in the workshop recently:

• BMW 1M – Investigated a persistent parasitic battery drain, traced to the factory alarm module. With the OE alarm now obsolete and unavailable from BMW, the system was isolated and left disconnected to ensure long-term reliability.

• Porsche 928 GTS – Undertook a comprehensive package of work including replacement of steering rack bushes, rear wheel arch restoration, and oil cooler replacement. All components were sourced as genuine Porsche parts to maintain originality and performance, with additional minor corrective works completed during inspection.

• BMW 535d (E61) – Completed a full ZF 6HP transmission service (fluid and filter change) alongside engine oil and filter replacement. The vehicle was then calibrated with a Stage 1 ECU tune and a bespoke gearbox remap to optimise drivability, torque delivery, and shift refinement.

• BMW 335i (N54) – Carried out a timing chain replacement. During disassembly, it was identified that the engine timing was out of phase, the result of friction washers having been omitted during a previous chain replacement. Corrective work restored proper timing alignment and long-term engine integrity.

Here at EAE we work on and fix all makes and models but specialise in German/ performance cars.

A couple of recent visits from the more race/track-focused end of the spectrum. 🏁

First up: E87 BMW
This one came in with some worrying steering/suspension noises, plus airbag and ABS warning lights.

🔧 Faults found and fixed:
• One bent and one rubbing front anti-roll bar drop link — both swapped out for custom links.
• Front shock bolts were rubbing on the strut tower at full lock. We adjusted camber via the top mounts and had it realigned by Martin

• Excessive play in the lower steering shaft UJ — replaced and modified to clear the aftermarket exhaust manifold courtesy of Jay .

⸻

Next: E53 Dakar Rally Car (Non-start issue)
Unfortunately this had been off the road for years and came in looking slightly sorry for itself, not starting and blowing the fuel pump fuse every time the fuel pump kicked in.

🔍 What we found:
• In-tank fuel pump was faulty and causing fuse issues.
• Tank full of old diesel sludge/gloop.
• High-pressure pump was blocked due to contamination.

💪 Our solution:
• Replaced both fuel pumps, filter, and high-pressure pump.
• Fully drained, cleaned, and refilled the tank.
• Fitted a new Bosch battery, fixed a parasitic drain, and installed custom front drop links & mounts from .
• Finished off with an MOT to get it back on the road.

A few long term projects getting finished and being picked up this week, the first being an engine swap for this 1963 Ford F100 short bed truck.

When the customer brought the vehicle it had rough running/ an intermittent misfire.

After abit of investigation it was found that cylinder 5/6 had low compression on the original Ford V8.

This engine was said to of been rebuilt but unfortunately for the customer it seems they did not do a good job.

However after throwing some ideas around the decision was made to fit a BMW M57 engine and automatic gearbox.

So the doner vehicle was purchased, the engine, gearbox and wiring loom removed.

Once everything was out and ready the process began with the help of our good friend Jay to get the engine and gearbox situated and mounted up with all custom engine/gearbox mounts and a full duel side exit exhaust system.

Wiring using all the original BMW front fuse box/ ECU housing and a complete custom loom for that complete OEM look.

The tank was cleaned/ drained and fitting with an AN fuel fitting for direct fit to the new fuel pump.

This now one of a kind American classic has a new lease of life hopefully for many more years to come.

End of an era here at EAE tomorrow we open our doors for the first time to our new workshop.

We have been quiet on socials for sometime and that is because we have been hard at work getting our new workshop ready.

And with the new workshop comes some changes to the way and where we are operating.

We now no longer offer mobile work, we are now strictly working out of our workshop in our new location of Farnham.

The new workshop is in the town centre of Farnham.

Unit 11, Farnham Business Centre, Farnham, GU9 7UP

Our operating hours are now changing as well to:

Monday- Thursday 8:30 - 5:30
Friday 8:30 - 5:00

We know this is a fair distance from our old workshop/ operating areas of Bracknell/ Wokingham and surrounding areas but we hope that as many of our customers as possible will make the journey.

We look forward to seeing you soon.

Many thanks from the EAE team.

Here’s a few of the bigger mechanical jobs done and the EAE workshop recently.

The first a 318i picture1-6 in for an intermittent misfire under load. After some testing the fault was identified as a worn valvetronic eccentric shaft.

The eccentric shaft was replaced with a good used second hand part at the customers request. Vehicle was put back together and tested and no longer had a misfire.

The second pictures 6-9 a timing chain replacement on a Mazda 2.2 diesel that came in with a EML and a fault stored for camshaft/ crankshaft correlation.

Timing chain was replaced along with an oil change, faults deleted and vehicle road tested, engine management light now off and vehicle back on the road.

Get in touch for any electrical or mechanical repairs required big or small.

Mini Countryman JCW All 4 in last week for a timing chain replacement for customer complaint rattling on cold start.

Upon removal of the cam cover it was found the camshaft was starting to delaminate and the guide rail had broken up so the sump then also required removal.

Being an all 4 the front differential required partially removing in order to gain access to all the sump bolts (thanks mini engineers).

With the sump removed it was cleaned out along with the oil pick up.

The chain, guides, tensioner and oil and filter were all replaced.

Vehicle was tested from cold but unfortunately still had a slight ticking/ rattle probably due to the delaminated camshaft.

Customer was advised to monitor and return if it proceeded to get worse.

Here at EAE we carry out all electrical and mechanical repairs and diagnostics, no matter how big or small.

So if you’re having car troubles get in touch to make a booking.
