NW VAG TECH are delighted to announce that we are now part of the Pendle performance network.

Pendle Performance are synonymous for high quality, safe, reliable  tuning for VAG vehicles.

NW VAG TECH has decided to partner with Pendle Performance due to the excellent reputation Pendle Performance has built throughout the VAG community.

All vehicles we tune are road tested prior to any work carried out.


A data log road test is also carried out where any underlying issues will be identified prior to remapping. once the data has been collated we can analyse this back at the workshop. This ensures we will not be adding a map to a vehicle which for example the turbo is struggling to produce enough boost on a standard map due to wear or other issues.  once we are satisfied with this data the mapping work can now begin.

Your vehicles original map file will be read from the vehicle using our specialist equipment. Then uploaded to Pendle Performance HQ along with a copy of the data log we obtained earlier. Martin at Pendle Performance HQ will then analyse the data log.  If happy Martin will modify the file for your vehicle with any custom changes carried out during the process.

once we have recived the modified file back we can upload this back into your vehicle.

A further road test and data log road test is carried out. this data log will then be assessed to ensure the Remap is working correctly and safely. we then upload this to Pendle Performance.

A official certificate is given with all remaps carried out by us which can add value and pedigree to your vehicle.

Pendle Performance… Done Right Done once!!

We stronlgy advise against anyone having a Remap carried out if these basic data logs are not carried out.




This is a throw back to a job we completed a few months ago.

A customer presented a 2011 Seat Leon with a check engine light on.

The same engine is fitted to many VW Audi Seat and Skoda vehicles.

We carried out a diagnostic check using our VAG diagnostic equipment and found fault code P0016 crankshaft/camshaft correlation.

Whilst carrying out initial diagnostics it was noted that the engine was abnormally loud. The timing chain was suspected to be the cause of this.

Using the correct timing equipment we set about checking the timing of the engine.

We confirmed that the valve  timing was not correct and could therefore rule out any sensor, wiring or control module faults.

By using a correct diagnostic method we were able to provide the customer with an exact quotation for the repair.

Our customer agreed to the repairs we advised. a Genuine timing chain kit was fitted, this kit includes a redesigned and uprated timing chain and sprockets along with a new tensioner.

Unlike many specialists NW VAGTECH have invested in equipment to replaced the crankshaft chain sprockets allowing the modified chain kit to be fitted.  Typically this would only be available at a main dealer. once the timing chain replacement was complete a minor service was carried out along with a thorough road test.

Our customer saved hundreds pounds compared to the dealership quotation.


VW Golf check engine light

This week in the workshop we had a VW Golf 1.6 tdi common rail in. Customer reporting the check engine light is on.  A diagnostic check s carried out  and found fault code P0403 EGR valve Exhaust Gas Recirculation Circuit Malfunction. The fault  traced the fault back to the EGR valve itself which requires replacement. We replaced the EGR valve along with all associated gaskets and seals. once complete we carried out a thorough road test and carried out a further diagnostic check to ensure that the fault has been rectified.
