🚐 Vauxhall Vivaro 1.6 CDTi – Excessive Oil Consumption… Found & Fixed Properly

This Vivaro came in using far too much oil.
✔️ No external leaks
✔️ Cylinder compression & leak-down tests all good

So instead of guessing, we tested further.

🔍 We found:
• Excessive end float in the turbocharger
• A partially blocked crankcase breather

Result?
👉 Oil being pushed through the turbo.

Out with the old, in with the new — and when we say new, we mean new:
✔️ Brand new turbo (no remanufactured units — we’ve seen too many fail)
✔️ New OE gaskets & crankcase breather
✔️ Off-vehicle DPF clean while access was available
✔️ Fresh Shell Helix oil & OEM filter to protect the new turbo

This is how we work.
Do the job once. Do it right.
That’s how we maintain high standards and earn long-term customer trust.

🔍 Testing. Not Guessing.

2011 Vauxhall Insignia 2.0 CDTI (A20DTH)

P2564 Turbo wastegate position sensor voltage low
P2002 DPF efficiency below threshold

This car has had faults for several months.
Up to now it’s had a DPF, Turbo, DPF pressure sensor, DPF Temp sensor & O2 sensor replaced.

It’s also been to a Vauxhall Main Dealer after these parts were fitted and had a software update.

The fault still persists, or does it, have the fault characteristics changed.

Watch the Video and see the diagnostic process used to rectify the issues.

Is reading fault codes a diagnosis to a problem?

2015 BMW 525d

Customer complaint : Intermittent Crank No Start.

This video will hopefully prove that reading stored Diagnostic Trouble Codes (DTC’s) is by no way a diagnosis of fault.

Also DTC’s must not be used as a shopping list for parts.

Reading of fault codes is only one part of our 8 step diagnostic process to conclusively prove the cause of the customer complaint.

If you’re having issues with your vehicle get in touch, book it in but please don’t expect “the computer” to hold the answer to your issue.

Extensive testing is the key to a first time fix with minimal cost to yourself.

DPF Removal v DPF Repair

If you’re considering have your Diesel Particulate Filter (DPF) removed and remapped you may want to watch the attached video from parliament in recent days.

The wheels are in motion with the powers that be to make the MOT test even more stringent regarding the performance of the DPF.

We as a business have never removed or deleted a DPF from a vehicle.

We have always opted to diagnose & repair the fault that is causing the DPF issue which is key to giving a long term fix to your DPF issue.

Refitting a DPF to vehicle that has previously had a removal or deletion performed is always far far more expensive than repairing the original fault.

If you’re experiencing DPF issues then please be smart about it and get in touch to find out how we can help you keep your vehicle legal.

Remember this when you have a conversation with a garage about DPF Deletion.

As the law stands, it’s not illegal for a garage to delete a dpf but it is illegal for you the owner to drive it on the public roads !
