We have had many years experience of 1980s and 2000s era Maseratis - from the earliest Biturbos from '82 to '88, through the well developed third series cars of '89 to '98, the awesome 3200GT from '98 to '02, and the efficiently modern 4200GT from '02-'06.

Due to the demand for the post-1990s cars we made a huge investment in a Sistema Diagnosi 2 (SD2) diagnostic computer. This is the official main dealer diagnostic system for the V8 cars, both Maserati and Ferrari engined - Quattroporte, 3200GT, 4200GT, Gransport, and Coupe - covering all cars up to 2006 and the major functionality of the post 2006 cars. With Maserati dashboards often lighting up like Piccadilly Circus whenever you turn the ignition key, be reassured that we will be able to quickly track down the cause and rectify it before it becomes an expensive problem. It even incorporates some SD1 functionality for the later six cylinder cars, such as the QPIV.

We also have the diagnostic equipment for all earlier Maseratis, going back to the earliest injected Biturbos - Marelli Unitest, Multitest, and Pro-One. Plus some stuff that doesn't even have a name.

We can rebuild the worn electronic throttle body throttle position sensor using the latest contactless throttle position sensor on site, whilst you wait. Meaning that it will never wear out again. We invested in the equipment to rebuild throttle bodies after experiencing a 100% failure rate on rebuilt throttle bodies supplied from Europe, and having to re-rebuild some for customers who had also bought them from Europe. If you bring your car here, we will remove, rebuild, install the throttle body, and clear the ECU using our Maserati factory diagnostic equipment. We rebuild the throttle bodies on site, and can do this whole process the same day. Possibly being the only place in the world where this service is available. Alternatively, you can send us your unit by post.

If you've lost the code to your factory Blaupunkt or Becker Radio/CD/Tape then we can decode it whilst you wait, or even over the phone - using magic.

Our Top Tips for 80s, 90s, 00s Maseratis:

  1. Change the oil. Use the correct fully synthetic oil, and change it frequently - more frequently than the rather optimistic service schedule if possible. The conditions inside a Maserati engine shred the oil pretty quickly. A non-synthetic oil will clog everything up and trash your engine. To change the oil filter you may have to remove the radiator on early V6 cars (for the full size filter, although there is a Maserati low profile filter that doesn't need the radiator removing, but supply from Maserati is sporadic), and the turbo ducting on later cars, so make sure this has been done properly with a genuine Maserati oil filter. The correct oil for the turbo cars is Petronas/Selenia Racing, and for the non-turbo V8s it's Shell Helix Ultra. We only use the correct oils.
  2. The later V8 cars have a 6,000 mile recommended service interval. On the V6s, they have a 6,000 mile service interval, but recommend changing the oil at 5,000 Km (about 3K Miles). I would suggest that this be applied to all engines with plain bearing turbos, so, early V8 QPs as well.
  3. Maserati say to change the cam belt every three years or 18K Miles. Cam belts deteriorate with time, as well as mileage, so make sure you change them rthat they are changed regularly.
  4. On carburettor cars, the fuel pipe from the plenum chamber wall to the carburettor has to go through a very tight angle, this leads to cracking and leaks, which leads to your car blowing up. Check it and replace it if there's any doubt.
  5. Dealer servicing of Maseratis is very expensive. I'm often asked why we're a lot cheaper. Perhaps you should ask the dealers why they're so much more expensive instead? We use original Maserati parts, and the correct Petronas Selenia and Tutela oils and fluids on the 3200GT and Shell Helix Ultra on the 4200GT. We do not cut corners.
  6. Radiators can leak. Not because the radiator is poor - on the contrary, it's extremely robust, but because the lower water pipe into the side tank can crack its joint. The rubber hose that attaches here needs to be removed when you change the cam belt and if the person doing the work is a bit rushed, then wiggling the hose to get it off will put a lot of strain on this joint and it will crack and leak. Having seen a lot of these - especially when a car has just had its cambelt changed at a dealership as they sometimes rush it. The other problem is that there are some interal rubber hoses between the two cores, which rot, and have plain steel screw clamps, which rust. We use stainless steel screw clamps. We can supply a fully recored radiator for £399 plus fitting.
  7. Starter motors have started to become a bit of a problem. As they're not really up to the job, they can suffer from a number of maladies, especially as they sit in the "V" of the V8 which can often fill with water from minor water leaks in the coolant distribution pipes that run under the inlet manifold. All this puts a bit of a strain on a motor originally designed to start a French shopping car (Maserati just changed the gear teeth pitch on the internal gearing). With a new motor from Maserati approaching £400 and the original manufacturer claiming not to make them any more, we can rebuild your old motor for £149. Fitting a starter motor is a more than challenging task, and should you not wish to go through all the hassle of removing the inlet manifold, fuel injection system, and much of the cooling system, we'll be more than happy to do it for you.
  8. V8 Service intervals. There is much chatter on the web about service intervals as the factory documentation dictates 6K Mile (10K Km) service intervals, yet the owners handbook seems to suggest 12K Miles (20K Km) intervals. The explanation is that the service regime in the handbook actually mandates a 12K Mile (20 K Km) service AND a 12 month service as well. So, if you were driving 12K Miles a year in a brand new Maserati 3200GT, the first service would be at 6K Miles and about 6 months, then after a year, and about 12K Miles, you would have a second service - thus having two services in a year and two in 12K Miles. The next service would be at 18K Miles, and about 18 months, the next at 24 Months and about 24K Miles. However, most people don't drive their Maserati like a rep's Mondeo and rarely manage 1,000 miles a month. So, a 6K Mile service schedule is good enough. The only service items that are "lifed" on age as well as mileage are the brake fluid (which absorbs water over time) and the cambelt which goes brittle with time. So, change your brake fluid every two years and your cambelt every three years, regardless of how many miles you've done... Some Maserati dealers will change various parts on age, rather than miles, when this is not necessary - such as Lambda sensors. These need changing after 60K miles, but are not time limited.
