Hello to all!

I have a SUN-DGA 1800 and tested the passwords here written.

Funktion tested for code 314159 15 minutes bypass and

the second code 515324 is for the service menue.

In the service menue you can edit date and after that you get full access back.

Hi, I've just acquired a pair of DGA1800s from a defunct dealership and want to get in touch with a Sun engineer able to test, re-calibrate and repair these machines.  Can anyone pass on details of an engineer if he is in the South East? I've been told that Snap-On also offer this service.

I am a small indy, restoring and servicing older Citroen and Peugeot cars. I need to test to MOT standard, but do not need the machines to be locked into the MOT system.

I see. So no-one got to the bottom of this then? It's now an out of date bit of kit (no-one uses it for MOTs anymore, do they?), so maybe the codes will be released one day.

I have stars where I would have expected readings. But this is with the probe in fresh air; I haven't tried analysis of an exhaust gas yet. Do these stars then disappear, or am I locked out? Did anyone figure this out when this thread was active? Cheers for any help you can offer; I'm just a home bike mechanic hoping to use the DGA to guide me with fuelling - the unit won't be used for MOTs or anything official.

No the leak test is optional. It just boots up, bypass the 10 minute wake up (314159), autocal and straight into the gas test menu. I hooked it up to a logic analyser to try to see what it was doing with the code, but couldn't figure out what to trigger on.
If it is failing the leak test I guess there is a pressure switch somewhere that is either disconnected or loose. You do need a long length of hose to keep the vacuum, I've got about 12 feet of hose on mine. Anything short (couple of feet) probably won't hold enough vacuum.

do you still have to do a leak check as well ,mine will not pass the leak check and its out of cal,i have tried blocking the pipes and creating a vacume whilst doing the leak  check but still says a leak is present but it holds a good vacume so cannot find any leaks ,so if i could get into the sun service i might be able to reset the machine ,i have found out that the code goes on the date ...

I've had mine apart, and downloaded the Eprom content. I will email if you fancy having a go at disassembling. Interestingly I accidentally shorted out the memory while poking around and it stopped saying it was out of calibration...result!! Now good enough to use as just a gas analyser.
