Cruise control finally sorted

I have had a problem with my Audi A4 cruise control for 18 months. One that Nobody could sort out! I contacted Hazzy dayz and they gave me two options which enabled me to finally get it sorted. Efficient, professional, knowledgeable company, with friendly helpful staff. Would definitely recommend.

Audi TT headlight upgrade

Travelled down from Matlock to have the headlights on my Audi TT upgraded. Perfect job done. Possibly not the cheapest but certainly the best in my opinion. Well worth the trip. Thanks to Adam and Doug for their friendliness and professionalism throughout.

Excellent service

Can’t recommend these guys enough. Went out of their way to help me retrofit camera based traffic sign recognition, which has now been installed on my 2021 etron. I had searched for a company to do this for me for a few months with little success or enthusiasm from anyone local. Gareth, Doug and David have been a pleasure to deal with and I would have no hesitation in recommending them.

GREAT SERVICE AND COMPETITIVE PRICE.

GREAT SERVICE AND COMPETITIVE PRICE.
Had been looking for electric tailgate upgrade on my Tiguan and had several quotes (non locally) but Hazzydays came back with competitive quote. I had also been looking a heated windscreen upgrade which others were not interested in, but Hazzydays came good on that as well. Booked in at a time to suite me and confirmation of all parts to hand.
Delivered the car to them, allowing two days and planned to return (by train) on day 3 to collect, but was ready lunch time on day 2.
They dropped me off and collected me from station, making the whole thing a good experience from a knowledgeable and friendly team.

Audi Q3 F3 front sensors

From the first contact with Doug in the office I knew these guys were very specialised in Audi retro fit work.

I had my Audi Q3 F3 booked in with Audi Eastbourne to have the front parking sensors fitted.

A few days before the job was due to be done they rang me to say it was not possible to do this on my car.

After speaking to Doug he assured me that it was possible as they had done this job many times already.

I traveled up from Hastings on Friday 3rd November for an an 11.30 appointment.

Adam was the technician that carried out the work. I’m sure he could have stripped down the front end of the car with his eyes shut.

Feeling very confident with what he was doing me and the wife went into Luton shopping centre to get some lunch.

A couple of hours later I got the call to say that it was all done.

A highly professional job from start to finish.

If you are looking for retro fitting for your Audi I can highly recommended these guys. Well worth the 100 mile drive.

VW Golf RNS 510 failure.

VW Golf RNS 510 had failed with black screen. Local garage couldn't fix and called VW and was quoted £4000 for new unit. Seems that the RNS 510 has history of failing motherboards and these are now unavailable. Andy and Dan were excellent and allowed me to hang around whilst investigation took place. They were very welcoming offering coffee etc. Andy eventually found a motherboard that could give everything but satnav and therefore reduced price of fix to a reasonable amount. At least we now have radio, hands-free etc and promise of any cost incurred would be offset against a refurbished/replacement item should unit fail under warranty. Very satisfied.

Factory fit quality workmanship

Looking for someone reliable to carry out some major works on our VW Caddy. We tried HazzyDayz for fitting Original VW Xenon headlights and was delighted with results, professionalism and quality of workmanship (just as expected from factory) this success story lead us to carry out some other major works 6 months later.
