BMW 320D / 520D 2.0D Diesel Pump EDC Repairs

Bosch VP44 (PSG5) Diesel Pump ProblemsBMW 320D / 520D 2.0D Diesel Pump EDC Repairs
The BMW 320D and 520D manufactured between 1998 – 2003 come fitted with the common failing Bosch VP44 (PSG5) diesel pump. This type of diesel pump has the diesel pump ECU / EDC (Electronic Diesel Control Unit) fitted to the top of the hydrualic/mechanical pump and is a very common failing part.

There are many faults associated to a failed EDC unit but below are some of the most common faults we’ve seen on failing EDC units, including the vehicle not starting:

  • Running Rough
  • Struggling to Start
  • Loss of Power
  • Engine Light On
  • Stored Fault Codes
  • Complete Non-Starter

When the Diesel Pump Control Module fails your dealer may advise that the units cannot be repaired and recommend replacing the Diesel Pump + EDC module complete. The cost of a new replacement part can be very expensive, will only come with a 12 month warranty and will require coding to the vehicle. Used second-hand parts are not recommended as the used part may also become faulty in the near future, come with a limited 30-90 day warranty and may require re-programming.

M20 / M32 Gearbox Bearing Noisy

Common M20 / M32 Gearbox Bearing Failures – Repairs & Rebuilds

M20 / M32 Manual Gearbox ProblemsM20 / M32 Manual Gearbox Repairs
The M20 and M32 Manual 6-speed gearboxes are extremely common failures and are fitted to a variety of vehicles including Vauxhalls, Alfa Romeo’s and Fiats. The most common problem is worn and noisy bearings which cause the gearbox to whine in certain gears. The noisy bearing may be more audible in some gears then others.

A noisy gearbox when treated quickly is not that bad a problem, we can generally re-bearing the box and have you back on the road in no time – but if you ignore a noisy bearing it can very quickly become a big problem.

Common M20 / M32 Manual Gearbox Faults

  • Gears Crunching
  • Stuck In Gear
  • Not Going Into Gear
  • Jumping Out of Gear
  • Noisy Gearbox (Whining / Grinding)
  • Gear Problems When Hot
  • Gear Problems When Cold

Although we’ve repaired hundreds of these gearboxes now, there’s many people that are not aware of Gearbox Repairs and will either pay out a lot for a brand new gearbox (which will come with a limited 12 months warranty) or pick up a cheap second-hand used gearbox (which will come with a limited 30-90 days warranty).

M20 / M32 Gearbox Bearing NoisyOur M20 / M32 Gearbox Repair Service
We offer a fast, efficient and affordable gearbox repair service. If your gearbox is noisy due to bearing wear and the bearing hasn’t yet completely failed i.e. collapsed and caused further damage then the repairs can be even cheaper than a second-hand part. We use new genuine OEM components when rebuilding gearboxes to ensure that each and every rebuilt gearbox meets & exceeds OE specifications.

All of our reconditioned gearboxes come with a 2 year unlimited mileage warranty and free fittings at our Gearbox Service Centre. For more information, call us on 0203 815 9441.

Mercedes B Class Gearbox Problems

Mercedes B-Class Manual Gearbox Repairs + Rebuilds

Mercedes B Class Gearbox ProblemsMercedes B Class Manual Gearbox Problems
The Mercedes B Class 5-speed manual gearbox is similar to the one fitted to the smaller Mercedes A-Class. The gearboxes are actually built to a very high quality and are quite robust so normally when they begin to fail it’s just because the bearings are worn out and need replacing. It’s always best to get the gearbox repaired sooner rather than later to avoid the bearings collapsing and causing further more expensive damage. Below we’ve listed some common problems associated with the Mercedes B Class gearbox.

Mercedes B-Class Common Gearbox Faults

  • Gears Crunching
  • Stuck In Gear
  • Not Going Into Gear
  • Jumping Out of Gear
  • Noisy Gearbox (Whining / Grinding)
  • Gear Problems When Hot
  • Gear Problems When Cold

Replacing this gearbox with a new part is very expensive and used parts may not be much better depending on how they were previously maintained – and will only come with a limited 30-90 days warranty.

Our Mercedes B Class Gearbox Repair Service
We offer a fast, efficient and affordable service to repair + rebuild the Mercedes B Class gearbox. When repairing the B-Class gearboxes we use new genuine OEM components to ensure that each and every rebuilt gearbox meets & exceeds OE specifications. All of our reconditioned gearboxes come with a 2 year unlimited mileage warranty and free fitting at our gearbox service centre.

If you have a Mercedes B Class with a manual gearbox fault, call us on 0203 815 9441.
