  • Volkswagen is inspecting 508,276 vehicles in the UK with regard to exhaust emissions that did not meet US standards.

    2.0 TDi and 1.2 TDi vehicles require a software update and 1.6 TDi models will require a small component to be fitted in the air intake (along with software changes). Either repair will take under an hour to complete. 

    Updates will be released in model batches therefore your vehicle may not be able to be updated for a while yet. 

  • Selective catalytic reduction and AdBlue®
    Some of our latest Volkswagen diesel cars have a Selective Catalytic Reduction system (SCR) installed. The system, which helps the vehicle meet Euro 6 emission standards, has a separate tank which contains a liquid known as AdBlue. Some vehicles have a filler next to the regular diesel cap while others may be located in the boot by the spare wheel well. 
    The AdBlue is injected into a specially modified part of the exhaust system in small amounts. This helps to reduce oxides of nitrogen emissions (NOx).

  • Colour coded for just £339.

    It's dark, it's wet or you simply can't always judge the gap, parking sensors are an invaluable asset to any vehicle these days.

    For just £339 we will fit and colour code rear sensors to your vehicle. The price is fully inclusive, so, unlike something that might be behind your car, there's nothing hidden.

    We can provide you with a free of charge loan car and the work can be completed in one day.

  • Your yearly MOT really doesn't need to be a stressful time. Regular service and maintenance should mean there'll be little to worry about. The test is designed to give you peace of mind about the safety of your vehicle. 

    We've put together a few basic checks that you can carry out at home in preparation. These and the more complicated items such as emissions, brakes, steering and suspension will be looked at by us during the test. If you're not mechanically minded, leave it all to us. We don't charge for small adjustments and fluid level top ups. 

  • We've teamed up with Herts Insurance Services (HIC) who specialise in Volkswagen Group vehicles. Based in Bishop's Stortford it offers a nationwide service whilst providing the local personal service you have come to expect from M J Warner Volkswagen.

    Established in 1989 HIC has grown from the original two members of staff to over 100. It is large enough to provide industry leading prices but small enough to care.

    Whilst 'online' quotes and comparison sites are all the rage, 70% of customers will obtain a better price over the phone.
